Wheeltextures flickering

[vonoben1944 0]

Ok so I have a sherman tank in-game and running fine. I based it on a BMP, so it was pretty easy just moving all the memorypionts around and change the naed selections to the new model BUT--->

The textures on the wheel flicker when I run. Looks pretty strange. It seems to be some kind of feature to give the impression of motion. I guess the brightness of the flickering is tuned to the BMP textures. Do any of you guys know how to change this?

(Also the tracktextures animate in the wrong direction but I guess thats just a problem with the UV mapping.)

maybe you have two wheels in the same place....probably not but that causes flickering, worth checking

Its not that kind of flickering. Flickering is a bad word maybe to explain this. Its more like the textureluminance is...pulsating between light and dark when the wheels rotate. It stops when the wheels stop. Its clear that ist connected to the rotation of the wheels, and that it is intentional... somehow. Noone else have come across this?

I have a problem on one of my vehichle but not on another. I'm not sure but I think it might caused by double sided polys. That is the texture is on two opposite faces. Its worht a look.

Ok. I just had a look at the wheels on the vehicle that was giving me trouble. It had 67 points and 64 faces. So that really didn't tell me anything. So I deleted all the faces of the wheel by selecting the wheel and pressing 'D'.

Next I re built the wheel by selecting 4 points per face the 'F6'. Once the wheel was complete I remapped the wheel texture. Made 3 copies of the wheel, positioned them in place of the old ones and reset their names according to whichever predni, pravy etc.

I tried it in OFP and the on-off luminance problem was gone.

Question: What program did you build the model in? The reason I as this that sometimes 3D (Deep) Exploration adds or subtracts faces on conversion to 3ds. Just a thought.

I'll try that... reimporting and stuff. I'm using MAX 4 to model and texture.

Sounds like the normals in the wheel's faces are not aligned properly... try selecting the face and do a recalculate normals thing, and also try to set it as a sharp edge (from surfaces/sharp edge menu)

i took a look at the m113 wheels and they look the same as a sylinder (F8) you only have to make it wider and skin it and your wheel is done

Now that problem is gone. And I didnt do a thing... stangely. I did however reimport the tracks since they were mapped with the V-direction sideways. I have no clue what happened.

Maybe you wanna see the sherman M4A3E8 I'm working on BTW. Here it is ingame.

I had the same problem with those pulsating wheels after I've remodelled the wheels for the BTR. So I did recalculate the normals, like Kegetys suggested, and after that it was gone. I realized that before the recalculation the engine somehow mixed both the shady and sunny conditins of the wheel and flipped them repeatedly. This caused the pulsation.

I did recalculate the normals on one wheel, just to see if it would work, but then they all suddenly worked fine so I'm not sure that was really the issue. maybe there's something else causing this after all.
