    3DCoat 4.9 BETA testing thread

    @Andrew Shpagin Just adding to what I said previously. The point of the sphere in the first place proves that displacement spikes exist.. all the UV islands may seem problematic but approximately 10 spikes manifested from that "extreme example" . Displacement can be sculpted and painted with other programs using that exact sphere without problems (Zbrush) for example but PBR painting is not Zbrush's focus and I'd like to work with 3DCoat's painting & smart materials etc. So again maybe if you could try to eliminate all error or incremental by a % of error if possible on something so extreme, the spikes are less likely to appear -better fix towards some than none.

    3DCoat 4.9 BETA testing thread

    The reason why I suggest you use it that model because it is the easiest model to show spikes exist and the best example model to get rid of random spikes even if you were to fix up to 50%. As I've shared with you, it doesn't give me *any* problem working with displacement in the other program (and I can post a comparison video of this if you like) but the other program , doesn't use rapid swapping smart materials and is my main reason why I choose to use 3DCoat. If it's just something you're not able to fix, I understand, no problem but it's sad as I invested in 3DCoat but I will no longer be able to fully trust/use 3DCoat anymore or at least not safely.. because like I've shared here that, I've spent days or weeks working on a project then these dam spikes randomly show up and you can't get rid of them and you then realize you can't use it for film, games or sell. That sphere I've sent you is pure gold, if you are able to solve that issue then random missing paint artifacts for others & displacement issues should finally disappear -3DCoat would be very solid... The additional rendering Candy in your 2021 release and all the extras are awesome but first take care of one of the core reasons why you have a paint room.. at this time while I love 3DCoat and the work you put into it, the program is not functional as intended.. as beta testers & regular users we've spent countless hours & find these critical problems at our own expense to help you improve 3DCoat. That sphere "DOES NOT" create spikes everywhere although you might think it will just looking at the islands, so yes although it looks like an extreme example it's actually what pros use for seamless planet, asteroid, moon textures etc. I hope you didn't just look at the islands and gave up, like I said it's not many spikes.. there might be a total of 10 spikes. Even if you were to tweak it to reduce spikes by 50% (down to 5 spikes on that model) we'll have more than a 50% chance on less extreme models that a spike will ever occur. I hope you don't see this request as unreasonable or pestering you, this is to your benefit as well as your other customers, there is a problem that obviously exists.. every model that I've used so far even with less islands has created this spike issue.. I've managed only to escape this issue on creating a model with only one island even on a closed model but done very carefully and isn't ideal due to potential for stretching. I hope you will give it a shot and maybe your tweak will at least make all other less extreme models work. In the meantime, Merry Christmas, happy holidays and wish you the best for the new year!

    3DCoat 4.9 BETA testing thread

    @Andrew Shpagin Hi andrew I thought I'd check in with you about the displacement bug to know a possible time table for a fix , for me this is SOS level and I believe I posted the issue there long ago but that was when I didn't have a strong sense of what was causing it or a model and procedure to reproduce the issue. Thanks for your help.

    3DCoat 2021 Coming Soon & Special Offers

    I've been stuck with a bug for a couple years, is essential to my workflow and likely other to have it removed. If you follow my posts you will see the time and effort gone into explaining them. I've also have a recent conversation with Andrew in my inbox about this bug. I have many projects incompleted, hours to days of work lost once the bug (black spikes) become visible painting displacement with smart materials, a problem I don't have in zbrush when working with displacement specifically but I need to work with photoscans. My finances are extremely low and the bug not yet fixed and it seems Andrew states he is now more committed to 3DCoat 2021 I'm afraid to put more money in at this point and have this an ongoing issue so I hope an upgrade compromise will be offered, i'm almost ready to give up on 3DCoat but I know it amazing scenes could be created with it once the issue is resolved.

    3DCoat 4.9 BETA testing thread

    I think this is the same kind of issue I've been having for the last couple years that i try to ask for help about.. but for me in those areas I'd likely get spikes and i think it's inverting the padding/black area on the UV.. In my observation the brush will get confused from jagged UV seams or topology and cause the seam/padding to expand .. in your case the missing color might be that you're trying to paint on the expanded padding. I may be wrong about what is causing your issue but it sounds the same. @Andrew Shpagin I've updated the conversation about this with you and Carlosan in my inbox. The example as you say may be extreme but these spikes happen randomly, maybe one or many more show, often after after hours or days of work.. you don't see them right away unless you use materials with a lot of depth. So I hope there is a fix for this soon.

    I just sent you a PM now, contains instructions how to reproduce & FBX file etc Thank you!

    Hi @Carlosan is there a hotfix or a new beta release available or coming soon to resolve the displacement bug I reported in my PM to you & Andrew?

    3DCoat 4.9 BETA testing thread

    I hear ya.. I've found what I believe to be the culprit and submitted the bug to Andrew. I know this is certain with displacement and in terms of undoing.. sometimes it's a matter of going to the menu to undo rather than shortcut keys or just another area if there is one depending on the function. I had to abandon a lot of projects over the past year or two.. I still have them and likely can be resumed/fixed once the bug is crushed. I think I may have broke Andrew with the bug report.. it might be a super challenge.. I haven't seen any updates for a while since.

    Thanks Andrew I messaged Carlosan and shared a model with instructions how to reproduce and the theory about displacement is being painted on Black marked padding, invertering the displacement etc. Hopefully it it can finally be resolved

    3DCoat 4.9 BETA testing thread

    Hi Andrew , just getting back to you with proof about glitches appearing painting with smart material with displacement. In this case it's not UVs, it's not texture output it's not the 3DCoat view window showing artifacts that won't be visible in other programs. Painting Displacement is fine in Zbrush, I never have this issue with it. . I exported this at layer 0, with displacement as an EXR This spike is visible in 3DCoat and is still visible in iClone. I could provide a link to my project so it can be examined, just let me know where to send it, thanks. This is a critical issue, i guess it happens when something isn't matched properly and this maybe the last hurdle to overcome to help make the workflow solid. This particular model is a sphere and the spike is happening at a pole, actually maybe again it is an issue with UV seams. It can be reduced with the height adjustment tool with magnification but creates such a huge drop it can't be smoothed , smoothing brings the spikes back. Maybe another hint how what's going on is that in the external 3D program if I offset the UVs it will change the spike size but the location is always the same and they are black so maybe the padding is getting displacement when it shouldn't?

    3DCoat 4.9 BETA testing thread

    I've installed the latest version but I have an old installation V 4.9.17 It does not show up in windows uninstall.. is there a utility to wipe it? and would this get rid of all my custom smart materials that have shown up in just about every other version since?

    UV mapping and spherical projection

    @Carlosan Spherical Projection is just not the same as splitting the UVs into beach ball islands.. I've tried this... I am working with animations and spherical projection allows the textures to flow and tile smoothly as if looking through a lens whereas the beach ball slices make the textures appear as if they are coming out of individual pizza slices. In Stephen's case you are probably correct unless he has some texture with spherical distortion/stretching. Even if you slice a sphere in half as two islands it's not a projection emulation. We would also need to orient the projection on YY or z axis on the model. Zbrush does this fairly well ignoring most of the topology but could maybe be improved as observed in the top and bottom. in this case texture stretching is required* for optical effects. I do have the latest beta of 3DCoat as of today but I don't see anything to do with spherical UV Projection. I'm not sure why the top and bottom didn't work but I would love to have a solution to fix this.

    3DCoat 4.9 BETA testing thread

    Thanks, it still doesn't work for AO. This might be an issue how it was designed to work by adding light /AO to the outside of objects but doesn't bake on tunnels.. this would mean a lot of crazy splitting / hiding meshes like the top half of a cave baking ao then making the underside visible only and baking that into a separate later then combining them.. I hope it could be baked onto the 2d UVs instead of examining all the 3D parts especially where it doesn't seem to bake.

    Another example, this time I UV unwrapped it in another program and I'm getting the same problem

    3DCoat 4.9 BETA testing thread

    @Andrew Shpagin Ambient Occlusion doesn't seem to fit to all areas, maybe it should scan the UVs rather than the model? I don't know how you make it work but here is my issue, the caves that i've created aren't getting the AO. I did use Auto UV upon import, perhaps that is the issue.
