Strange texturing

Thanks for the advice, it has solved my latest problem too. The face just above the windows of these coaches just would not go right, shaded this side, and lit up on the other (see first pic). Recresing just did not solve the problem.

After reading this thread, I triangulated these two faces, then recreased the whole coach body object and ‘presto’ it was fixed (see second pic).

Attached is a screenshot in MSTS of a simple model. Note that some of the side sections of the model are shaded differently than others. The base color of the source bitmap is uniform.

I do note slight shading differences on the untextured 3DC model. There are no un-needed points on the model and the bottom polys have been trimmed.

The model has been optimized, cleaned and creased. I’m using 3DC 5.7a. Any advice on how to cure? Thanks in advance.

troub,

Thanks for the pointer. No extra points on the edges, I trimmed them as a matter of course as I have seen the effect you mentioned. Triangulation and optimization did the trick as recommended by FozzyBear.

This was the first I’ve had this problem in about two dozen buildings, two engines, a handfull of rolling stock, umpteen signs, and a dozen or so bridges. I now know what to do if it happens again andnbsp; .

If I had to guess, I’d probably say your problem was caused by extra points on some of your edges. andnbsp;I have noticed this can cause some strange shading problems. . . andnbsp;You may have done some andquot;divideandquot; operations and missed deleting a point or two when deleting an unneeded edge?

Thanks FozzyBear, triangulation followed by optimize and re-texturing did the trick.

Try triangulating and then optimising all of the parts….

If you have optimised and then creased all the object parts to the same level then All I can suggest is that it may be a material properties question….

Try using the material picker (dropper icon) on each of the faces and make sure that they all have the same lighting properties set….

Glad that solved your problem ….. I’ve come across this one a couple of times, prticularly where an object has had faces removed or been part of a Boolean operation. For some reason optimise alone doesn’t catch all the stray points. What you can end up with is multiple points at the same coordinate and optimise ignores them if they are. andnbsp;That also makes them hard to spot manually.
