So any face that is textured using a texture with a bump map must be correctly face mapped.
I had a lot of faces to re-map as well DOM107.
In the end I re-modeled and re-mapped the faces with the rivet bump maps again as there were fewer of these than the black faces across the entire inside of my cab
Hello,
Example of a textured object:
A) Use the fill tool
Use brush for specific face texures
Faces textured with the fill tool show in uv remap only 2 points joined by a line.
It’s not a problem in 3DC but in RS asset editor, faces are black.
So I had to retexture the black faces with the brush + Face coordinates.
Any idea of what could be wrong?
I think you have to be using face coordinates when you use uv remap
I had this exact problem with a cab I was building. I used the fill tool on the deformed object I created and thought that looks nice, I’ll leave that. Using TrainSpecEnvMask.fx gave me a nice shine on the paintwork but no rivets which I had bump mapped. I changed the shader to TrainBumpSpecEnvMask.fx and added a bump map. I got my rivets but a lot of faces in the cab turned black just like yours. After going back to the model and unwrapping those faces using the face coordinates mode and retexturing this cured the problem. The problem only occured for me if I had a Bump in the shader name.
This is most probably because RW has no mapping coordinate information for that face ie it’s expecting at least to see a three point triangle so it can get the mapping coordinates off it. As you said, if you only have two vertices joined by a line in 3DC that doesn’t contain enough information for RW to work out the mapping coordinates and just gives you a default black face.

Yes, you’re right.
Can 3DC export do something about this as it means a lot of rework for faces which actually only need a color but which are part of a shape using normal maps?
Or a new way of filling faces for objects textured with the Fill Tool.
The blackness is actually caused by the bump map having no difference in UV to calculate the shading.
A non-bump shader would have no problem with this.
So, what do I need to do for this? Anyone know?
This is not a problem with 3DC – it only happens where bump maps are not mapped correctly.
It’s needed to texture group of faces using Face coordinates.
We need a tool able to fill a whole object in one step using Face coordinates.
Why not the Fill tool taking into account "face coordinates"?
And also to texture a group of faces using UV Map, UV Map should take into account "Face coordinates" (I haven’t check if it’s working w/ 3DCrafter).

To texture a group of faces using Face coordinates is actually fairly complicated to do well. I agree it is needed, and have done lots of research on how to do it exactly. There will be a tool that does this eventually. Hopefully in 3DC 9.1.
The UV Map operation, and fill operation do take into account face coordinates.
Ok… so basically there is nothing specific for me to do about this. There are other issues that contribute to this, but it’s not a problem with the exporter. I understand.
