The scene Motion_blur.ma contains a short animation of pool balls. In this tutorial, you'll render the motion-blur example scene provided by SolidAngle. There are no real similarities between them other than initially being built in the same maya scene.If you haven't already done so, Download the Companion App. :(ĭoes anyone have any idea what might be going on here, or how to fix this issue? What makes normals "invalid"? It's happened with two different meshes for me now and is driving me a bit nuts. It's unfortunately not a permanent fix- if I import the new re-exported fbx in Maya to edit it, and then re-export it from Maya and import it into Painter, it gets messed up all over again. I have no idea why this works but it seems to magically allow Painter to read the normals properly. The only thing I have tried to fix this successfully was a tip I found in an old reddit post when googling the issue: importing my fbx into Blender and then just re-exporting it from Blender. Often after doing one of these troubleshoots, I then get additional error messages in Substance saying that my tangents / bi-normals are invalid, as well. Resetting fbx export settings and ensuring that normal data is being exported properlyĭoing a mesh cleanup to make sure there isn't any nonmanifold geometry The classic "cube trick" (combine the mesh with a cube, delete the cube faces)
and then re-doing all my custom hard/soft edges and re-exporting to SubstanceĮxporting as an obj, re-importing into a fresh Maya scene, and then re-exporting to Substance Unlocking the normals in Maya, averaging them, setting them to face, etc. Here are some things I've tried, unsuccessfully, to fix this: The mesh looks correct in both Maya and Unity, as well as in Blender. My mesh has a lot of custom hard / smoothed edges, and when I bring it into Substance it basically softens all the edges, leaving it looking pretty gross. and then re-calculates the normals itself. "Mesh normals are invalid (some values are null) and will be recomputed" I'm encountering an issue I can't seem to find any documentation or posts about: when I import certain meshes into Painter, it tells me: Hello! I'm experienced with Maya and other 3d programs but am fairly new to using Substance Painter.
