corona decals troubleshooting

[Erich]

Hi guys. I am having problems with Corona decal materials. I have a few (4) very simple graphics that I need to be placed on my model. None of them seem to be working. I have assigned a material to the decal objects and also added the decal png files into the map slot of the decal object. However, only 3 of the 4 decals appear on the model. They all have the same settings, just the image files are different. The one that is working isn't showing in the correct color (it should be a bright orange).

I know its probably something simple that I am overlooking, but I can't seem to find what it is. If anyone can please help out, that would be very appreciated. I seem to always have problems with using Corona decals, and really wish the implementation of this would be a lot easier as I think it is a really valuable tool. It just seems more fidgety than it should be. But alas, its probably just me. :).
I have attached the Max file.

Thanks for helping.

Hi,

I quickly checked your scene, and it seems there are no CoronaDecal obejcts in there, there are simple editable poly objects.

You need to create a Corona decal object (it is a box like object with the texture, if applied, being displayed on one side) and assign the material to decal object.
The decal's bounds will tell how "deep" the decal will be projected.

Besides this, I also saw materials set up to be refractive - if a material is fully refractive, it will not have the base layer, where the decal texture usually is.
I have modified the scene you sent and used procedural textures to demonstrate it.
Hope this helps.

Hi Aram. It is really odd that you don't see the decal objects as they are most definitely there in my scene files. Maybe something happened when I exported the file (I used the Archive tool in 3ds Max). But thanks for your help.

Hi Aram. As I suspected, the file I originally uploaded here was incomplete. However, I was able to figure out the problem. Turns out it was an issue with the graphics that I was using. Cheers.
