I made an simple fence placeable the problem now is that when placed it has 2 different shades when placed in an exterior area looks normal in an interior. You can rotate the placeable 180 and the shading from the same facing changes dramaticly. Not sure what the problem is? It looks fine in gmax I used an material with the default 100 diffuse color and 30 bump.

Is it the same thing I was talking about here:

If so, it is the directional lighting in exteriors.

It might be the thing is that if you just rotate the placeable it has an different shade compared to if you just left it alone. These placeables when placed side by side appear really different.

Heres an picture of both side by side

Ok. If they are facing in the same direction and have different lighting, then your problem is not the same as mine. Sorry I could not help...

Are they rotated 180 degrees out from each other? In other words, did you flip one around for the sake of variety in placement looks? If so, it could be the way you defined their initial parameters in GMax. I believe in GMax (not real sure) that the shading is determined by their initial modeling position in the application. I don't really know for certain, but it does appear that if you did rotate 180 and you have this very clear and obvious shading issue that you might have to go back and retweak your shading parameters in GMax on your model and make it shadow neutral.

I do have the GMax Handbook here and can attempt to reference anything relevant for this if necessary.

Spent an few hours trying to tweak this model trying various things in the material editor but still having no success. Not really sure where to go from here.

In that screenshot you posted - is that the same side of the object in the two instances, or is one turned around?



Off the top of my head, check to see if any of your texture maps have an alpha channel, particularly the normal map.

One of them is turned around 180 here's an better pic

Well that is certainly strange.

Again, it looks to me like you might have an alpha channel in your normal map, or tint map (if there is a tint map). If your textures are mirrored , it rules out the alpha channel problem. Both sides would have that same issue.

Does it have its own 2da entry, or did you override an existing placeable?

Some other things to check

1. Are your diffuse, ambient, and specular colors set to all white in the material editor in 3ds max or what ever modeling tool you use.

2. Since its all flat sides, clear all smoothing groups.

3. check for duplicate faces on the darker side in your modeling program.

4. check to see if all the tint colors under your item properties are set to all white. (even if it doesn't have a tint map)

Tried the stuff hellfire_rws said but no luck. Think artechoke is right and its something to do with the alpha channel. I do not know much about alpha channels with gmax.

[Hellfire_RWS]

Alpha chanels are applied to the texture in Gimp / Photoshop, its part of the texture iteself

I still cann't seem to figure this out. Is there any chance that anyone has an simple model already setup up in the gmax format that looks fine in the toolset and is willing to share. I would like to go over it and see if there is something I over looked some where.
