Decimating Mesh - What About Texture?
« on: June 24, 2020, 07:14:03 PM »
I decimated a mesh from 25 million to 15 million faces (it was of a group of buildings).  The geometry of the buildings looks good but the texture looks terrible.  (Texture was arbitrary mappying 10 X 8192px mesh pages)  Do I need to regenerate the texture after decimating the model?

Took a while to process but I tried it and the answer is yes, you have to regenerate the texture to better fit the decimated mesh.

Hello jazzyj,

Texture is discarded when Decimate mesh command is used.

However, instead the texture re-building from the images you can use texture transfer option, if the high resolution textured mesh has been kept in the same chunk.
