  2. Baking an AO map just gives me a black texture

    in Questions & Answers

    Posted

    This is the UV map, on a brand new model.

    This is the AO map at 1024

    This is the Curve Map (default settings)

    I was trying something that I thought was causing the issue (importing from maya while all the objects were in a group in maya). That didn't do anything, however, it did create an interesting result.

    A DIRECT import from maya with these settings:

    Had the following default UV's (I didnt create them so I am assuming 3DCoat is auto doing it?)

    And without doing ANYTHING, just going directly to bake an AO, this is the result I would get:

    So, that makes no sense....

    Out of curiosity, have you checked your scene scale for any of the models which aren't working?

    I ask because there seems to be some relevant information in this thread...

    Also, have you tried baking a curvature map to see if those results are also incorrect, that may provide some clue as to what type of issue you're facing?

    I will try that, but I am doing the normal size for UE models. Would seem odd, but it might be related since I have other issues related to UI import and export. Let me tinker a bit and will get back to you.

    Can you do a test and see if it is the UV's? A black texture almost always points to that. Go to the UV workspace and for each UV set (a drop list menu in the upper left, just above the viewport), click the UNWRAP button in the tool panel. Once that is done, click APPLY UV SET. Now, go back to the Paint Workspace and try AO baking once more and see if it works this time. If it does, then that means there was something fudged with the UV's prior to this test.

    As far as I can tell, no issues with my UV. I will re-unwrap them just to be sure. I think it has to do with smoothing groups. My import settings might be the reason for it, since I can get the textures to spawn correctly when I tick some of those settings off/on. I still get black with these UVs unwrapped and applied. However, if i export and import and lock normals and generate smoothing groups... I can bake an AO. The AO is blocky and not really proper. If I turn off the setting for generate auto smoothing groups I still get the black issue.

    THIS IS WHAT IT LOOKS LIKE IN MAYA WHEN EXPORTING:

  8. [Solved] 4K Display startup

    in New Releases, Bugs Reports & Development Discussion

    Posted · Edited by riuthamus

    It sounds like the same issue, but that driver has nothing to do with my setup. I do not have the same things he does. I will, however, find the audio driver and attempt to turn it off and back on and see if that has any change/effect.

     

    **EDIT** - That somehow worked. I am not using a Cintiq, however, I am using a HUION and when I turned off the audio driver and started the program I had no issues. Why that works/fixed it... I do not know but seems good for now. Let's hope this does not affect my streaming :P

  9. [Solved] 4K Display startup

    in New Releases, Bugs Reports & Development Discussion

    Posted

    So, recently I got a new Huion 4k display and got it all set up. When I moved my 3DCoat over to the display, all was good. However, upon closing the program and opening it again it just sits on a white screen and times out. I have to force the program shut and then, it won't work at all until I delete the folder. Once the folder is deleted it loads up on my ULTRAWIDE monitor (that is not 4k) and I have no issues. I can replicate this every time.

  11. [Solved] Z Direction Up

    in General 3DCoat

    Posted · Edited by riuthamus

    @Emi not sure if you watched the video or not but clearly that wasnt the problem. The face issue was related to the normals and importing normals from Maya over. It works flawlessly when I do not import with Z axis up. So, there is an issue with computation of normals upon import of only when exporting using Z axis from maya. I will check to see if there is something I missed on export of the FBX but the stuff mentioned doesnt seem to be linked at all.

    I looked and it was not set to Y, changed it now and will be testing, results to be posted shortly.

  15. [Solved] Z Direction Up

    in General 3DCoat

    Posted · Edited by riuthamus

    So, recently I wanted to make my models in Maya using Z direction up. This makes for importing into UE4 much easier, however when I do this and I try to import into 3dcoat I am no longer able to paint the model properly. It is like the normals or something get jacked. Has anybody else had this issue?

    This is the import settings:

    This is the result

    This is what it looks like in Maya when I export it

  17. [HELP] UV MAP more than one object

    in General 3DCoat

    Posted

    So, I am attempting to make a model that has the facial elements (eyes, mouth, eyebrows) on a different set of models. The main reason for this is that I want to make those elements changeable via our game engine, but to save space I want to try and put all the eyes and mouths and such on the same diffuse/normal/roughness set of maps. How would I go about doing this in 3d coat?  a quick search didnt turn up much so I probably dont know what the right thing to ask is... If you need me to explain this better or show pictures/video to explain what I want to do, let me know.

  20. [Solved] Painting - Symmetry Not working

    in General 3DCoat

    Posted · Edited by riuthamus

    I have never ran into this... but symmetry works on some parts of the mesh but not on others. I orignally thought this was related to a layer of information being hidden or something... but it doesnt seem to be the case. If i make the brush bigger it works, but then i go back to the finer detail and nothing. Any suggestions?

     

  22. [Solved] Load UV Map After Model Changes

    in General 3DCoat

    Posted

    So, here is what happened:

     

    1) Created the model and loaded it to 3dCoat for uv mapping. After marking seems on most of the object I noticed I had some duplicate mesh stuff going on. I saved the UV map with the Save button in the UV room.

    2) Went into Maya and fixed the error by deleting some faces.

    3) Started a new 3d project and imported the mesh again.

    4) Went into the UV room and used the load button, chose my UV map I had saved

    5) When it loaded all seemed to be good and life was happy. Until, I noticed that it loaded the old model with the duplicate geo.

     

    So, here is my question:

     

    Am I able to get the previous Seem work from the old model onto the fixed model? There is about 30 - 50 min of work in that and wanted to try and not redo that process if possible. Thanks for any help you can provide.
