No matter what I do, the face will be invisible in-game. Tried this with both .bmp .png.Use 'TEXTUREPROPS 1 1 1 0' to make texture page B use mipmapping, support mapping outside the boundaries and disable colorkeying (no pure-black alpha testing).
Added in version 18.0428a.
Yes, I have the lastest version of RVGL, and no, didn't use alpha/translucent flag on the image/face.
Uploaded the test track.
