 Post: #1 [Solved]Decals and wheel trace Hello, I'm trying to add wheels traces by using decals and I have a little question about drawing my traces. http://img26.imageshack.us/img26/4130/scrsh4.jpg As you can see some decals are extended or narrowed. I've checked tutorial and I saw thet when I shot between barrel and ground I have similar effect: http://img294.imageshack.us/img294/4130/scrsh4.jpg This is part of code which create decals: Code: `Game::World.terrainAddDecal(WHITE,Materials.ptr("Gfx/Trace/Trace.mtrl"),wheel[2].matrix());` Is here something wrong?

 Post: #2 RE: Decals and wheel trace Problem aboive is solved. How can I rotate decals which I put on the terrain? I tried some transformations with matrix but it doesn't help.

 Post: #4 RE: Decals and wheel trace http://img689.imageshack.us/img689/4130/scrsh4.jpg 1st code: Code: `Game::World.terrainAddDecal(WHITE,Materials.ptr("Gfx/Trace/Trace.mtrl"),Matrix().setRotateY(T.matrix().angles().y).move(T.wheel[2].matrix().pos-Vec(0,0.2,0)).scaleOrn(0.3f));` 2nd code: Code: `Game::World.terrainAddDecal(WHITE,Materials.ptr("Gfx/Trace/Trace.mtrl"),Matrix().setPosDir(wheel[3].matrix().pos-Vec(0,0.2,0),Vec(0,1,0)).scaleOrn(0.3f));` In the first code as you can see traces isn't draw properly but they are rotating. In the second code I tried many ways to rotate this but I failed. Could someone give me an advice? (This post was last modified: 09-13-2010 06:47 PM by Harry.)

 Post: #5 RE: Decals and wheel trace Well maybe u can try it with Lerp() so it interpolates between 2 decals. But what i think about your first code.. its looks like it that the decals turns in the wrong direction. There is always evil somewhere, you just have to look for it properly.

 Post: #6 RE: [Solved]Decals and wheel trace Thank you Dynad for give me a clue. I rotate decals in y axis by 90 degrees and now they are drawing ok
