Texture does not render in LDCad 1.6b


Texture does not render in LDCad 1.6b
#1
Hi Roland, and others,

I have LDCad 1.6b running and configured like it should, but no texture is rendered on textured parts.
I still have LDCad 1.6a running on the same machine that uses the same libraries and there all my custom texturemapped parts render just fine.

What could be wrong?
I obviously checked and made sure Texture mapping was enabled in 1.6b.

The only thing changed regarding textures between a and b is generation of mipmaps. So this could be a driver thing.

Did you use the same main.cfg for both versions? You can force that by (tmp, rename the a version exe) placing the b version in the a version's bin folder.

Hmm, OK. I did not use the same main.cfg because I have set up 1.6b like a fresh install.
I did make a copy of the LDCad.exe for 1.6b and placed that in the 1.6a folder (after backing up the original indeed ;-)

That did the trick. Textures render fine!

Now what causes that?
The only true difference (besides window state, last openend files, etc) between the two setups I could find was in the main.cfg [LDraw] section

vertexProcessingMode=smooth (1.6a)

vertexProcessingMode=none (1.6b)

Setting it to smooth in 1.6b did the trick in the 1.6b setup. It now renders textures fine too... ;-)

Ah I forgot that restriction, the none mode does zero post processing on the LDraw xyz coordinates, this includes generating the uv parameters.
