Reputable Contributor Silas Merlin Posted November 24, 2019 Reputable Contributor Share Posted November 24, 2019 Someone asking how to export just one paint object..... I feel so stupid having to tell them to delete paint objects, export, reopen saved file, delete other objects, export, etc.... This makes 3dc look bad, really.... :( Also, I believe 3dc could safely assume that it can hide your sculpt objects for you when you do this : Bake in retopo room, then move to the paint room. 2 Link to comment Share on other sites More sharing options...

Contributor Ascensi Posted November 25, 2019 Contributor Share Posted November 25, 2019 (edited) @Andrew Shpagin @carrots comparing 8bit, 16bit and 32 Bit output for displacement using the Grey-based, not normalized the 32bit appears in photoshop as if its missing data shown in the map with red dots but if you look at the other map examples you will see them more like greyscale and more filled in. I spent some time showing what the outcome of each looks like and maybe I'm wrong or doing something wrong but the EXR and Tiff output looks multicolored.. is this normal? I'm not exporting with vector displacement. You will also see the glitchy areas. 8Bit BMP looks almost perfect but cracks are visible. The 32 Bit files even with export constructor doesn't load into photoshop or iClone with any gradient in red monochrome like Reallusion's example In the files I've generated it looks like its missing data. I'd privately share a couple of my projects if you want to test them/test in iClone. This is apparently how it's supposed to look in iClone (notice the Red texture in the displacement channel) : Edited November 25, 2019 by Ascensi update Link to comment Share on other sites More sharing options...
Andrew Shpagin Posted November 25, 2019 Author Share Posted November 25, 2019 You should use export constructor. Choose Mono, 32 bit. Assign displacement. All that is available ONLY through export constructor, not via separate texture export. I opened exported exr file in PS, it looks correctly. And it is black - based, has negative values if displacement is negative. Link to comment Share on other sites More sharing options...

All that is available ONLY through export constructor, not via separate texture export. Yes I have, I've shown the comparison,(the bottom of the second picture) it doesn't show properly in iClone.. the detail of maps using the exporter in photoshop isn't there and when in iClone isn't in red with EXR. Displacement glitches are seen. I've recently exported with mid poly mesh (20 MB) and most of the errors are gone but it kind of defeats the purpose. There is a compatibility issue here. The latest example was created using half the amount of subdivision available and I increased the tessellation just to see if greatly increased subdivision levels were causing deformities in the exported maps but the same problem exists.

Andrew Shpagin Posted November 25, 2019 Author Share Posted November 25, 2019 And I don't understand gray based, not normalized... What if displacement is <-0.5? So in export constructor I use only black-based not normalized. If someone will explain me about gray based, I may do it. Link to comment Share on other sites More sharing options...

Reallusion support doesn't understand normalized and not normalized, Zbrush doesn't even have it. Personally it doesn't matter to me the method so far as it just works but Reallusion's EXR displacement seems to require just red but the detail is not there maybe because you are using black-based not normalized. They do have other basic displacement textures that the output in photoshop looks like this: Reallusion or myself doesn't understand what your normalized/not normalized option does but it makes me think it's doing some kind of brightness/contrast adjustment and the Reallusion textures seem to require 50/50 greyscale Link to comment Share on other sites More sharing options...

Reputable Contributor Silas Merlin Posted November 25, 2019 Reputable Contributor Share Posted November 25, 2019 (edited) Is making voxels non transparent in flat shade mode a technical impossibility ?

Advanced Member L'Ancien Regime Posted November 26, 2019 Advanced Member Share Posted November 26, 2019 (edited) I disagree. I don't want to see Andrew get sidetracked into wasting his time on building a render engine. At best he should either embed Radeon Pro Render into the 3D Coat workflow or make a really efficient plug in to render your 3D Coat sculpts effortlessly in EEVEE or Cycles in Blender. He's already got a partial implementation of Renderman into 3D Coat. He could just add on a more complete set of Renderman controls into the 3D Coat interface we already have. It's free, it's top quality. No need for more than that. Take a good look at Zbrush which has far more resources than Andrew for development; they're not wasting their limited resources over their BPR renderer. They've got a good plug in to Keyshot and they're letting Luxion do all the necessary specialized work to develop Keyshot. And nobody among the vast pool of Zbrush artists is complaining about that.

Advanced Member insignet Posted November 26, 2019 Advanced Member Share Posted November 26, 2019 Its a valid point, but why not jump into blender for modelling, sculpting, retop, UV 'ing and rendering?

Jack of all trades, master of none. Too late. He's had one of his developers working on it for a while. As has been mentioned in the post before yours, one of 3DCoat's biggest markets is Concept Art. Andrew can lock this market down with a great built in render. I agree about the prospects for other engines like ProRender, but from what I understand, that has been explored. A major limiting factor was using large models with millions of poly's + PBR shaders + Smart Materials, etc. 3DCoat can handle that much better internally, than exporting to a standalone render engine, like it has to with Renderman. That is why the Renderman integration, as nice as it is currently, is still very limited. I'm not sure, but I think the new render engine might be able to render in the viewports, which would be HUGE. Link to comment Share on other sites More sharing options...

I would also like a way in the paint objects section to re-order the list. Sometimes I have a lot of paint objects and having to scroll through and find each one toggling them off and on again can get tedious. Either a way to re-order, color code, or put in sub folders would be a great way to organize them more for sure. But I agree, being able to export just one paint object would be a good option as well. Link to comment Share on other sites More sharing options...

Adding Cycles free would be nice but I'd pay extra for an Iray plugin, it uses all CPUs and GPUs together, takes advantage of RTX OpitiX for realtime Raytracing wit AI denoising. It works very well with iClone. I also have keyshot 5, Indigo render and, Octane but overall I think I like Iray best for easy setup even for complex scenes.

Contributor Ascensi Posted November 27, 2019 Contributor Share Posted November 27, 2019 (edited) Displacement now works perfectly with the Grey -based red monochrome! Big thank you to Andrew!! One last issue I have was the default normal map is messed up! I've read some other users find a solution for blender such as setting non-color data but I found a temp solution for iClone which messes with the brightness etc. Can a proper default Normal map be generated without having to change color values externally? Here is my temp solution: Actually there is one more thing. Is there an option to set the smoothing angle to a project that has already been painted? is this even possible? There are other projects already painted that I need to convert. I spoke too soon.. I looked closer and found a mismatch Edited November 27, 2019 by Ascensi update Link to comment Share on other sites More sharing options...

Maybe mixing different smart materials with different normal map types mess up the final output? if so maybe custom import settings for the Smart Materials UI should be added so 3DCoat can identify and convert all the normals to the same type on export. The outside of the model texture1 looks absolutely fine when exported but the inside (second texture) was a different smart material likely with a different kind of normal although looks fine in 3DCoat. I thought it had to be an issue with the textures.. below an example completely fixed with using a different smart material belonging to the same texture database. Not only that, I no longer have to worry about play around with the RGB settings! Edited November 28, 2019 by Ascensi Link to comment Share on other sites More sharing options...

First of all, I want to congratulate you and your developer team for everything. I know you just posted this new stable release, but you could kindly inform all artists that they are completely anxious about the great features and tools that will be released in the program. What can we artists know (if you can talk) about what is really coming in the next versions going forward? What could I come up with in the Sculpt Room, Paint Room, Render Room, Retopo Room? Will the geometry be more unified (can the artist edit polygons, sculpt and so on the same mesh) and so can have UVs in that geometry? We can paint Displacement Maps (similar to Foundry Mari) and then we can use and non-destructively apply this displacement map to a geometry by physically modifying it in Sculpt Room? What will be the main functions of the new Brushes and Alphas system? Can we have functions as important and essential as there are in other programs so that the artist can carve and detail the characters, objects and scenarios with much more quality? What can we expect from Sculpt Layers? Will we have the implementation of OpenCl? What will we have in the Paint Room? Will we have the interface, menus and palettes that can be completely customized by the artist and thus optimize the interface according to the artist's work? Will we have something similar to Modifiers that allows the artist to work non-destructively and in real time? Sure, there are a lot of other things, but what can we have in future releases?

Contributor Ascensi Posted November 29, 2019 Contributor Share Posted November 29, 2019 (edited) @Andrew Shpagin Feedback on export constructor 32 Bit EXR Grey-based, not normalized VS non export constructor 32 Bit EXR Grey-based, not normalized both are monochrome red (awesome) but! the 32 Bit EXR Grey-based from export constructor produces spikes (its vivid or stronger contrast) but the non export constructor 32 Bit EXR Grey-based works perfectly! At the moment I'm using 3DCoat DX version and was trying to understand why my files were coming out spiky again after you suggested that i should be using the export constructor. So initially when you created the fix it worked but I wasn't using export constructor. When I was using export constructor 4k EXR worked fine but not for 16k and with 16K in general I had to reduce the multiplier from 1.0 to .5 to get it to scale properly Export constructor has other color information and you can see it if you increase the levels in photoshop but if you increase the levels on the file without export constructor you will see the whole image get dull and bright. I noticed that the Texture baker doesn't have the "Auto Smooth Groups angle" option, is this automatically applied when baked? I have projects that were not set with the smoothing angle that they need.. are they irreparable???? I wanted to bake them to a new/better mesh and use displacement but many of the projects didn't have smooth groups enabled. When you have the time would you mind adding an option to rotate the HDR enviroments Vertically? I'd like to be able to work on painting underneath the model.. I tried flipping a map in the past in Photoshop but it didn't work for me. Also if you're looking for some breakthrough ideas to outshine competitors, may I suggest the option of having "procedural animation materials type" that can be baked but allow use to paint these animated procedurals while also seeing them animated but have the option for play/stop. There are some very fast Video codecs that the game engines have integrated like (HEVC) I don't know if that is ideal/plausible but it's a concept.
