More problems applying maps - 'decals'

[magnatizerr]

I still seem to be having problems applying maps or 'decals' onto objects using the RCM tools to map.

Here's my problem:
Image one shows a simple sphere with a 'square' map applied using RCM. (note the 'diffuse' colour is full black in order to get the opacity in the image - ie no 'washout')



Illustration two shows a 'shaped' image used in the 'Transparency' slot of the 'Diffuse' area (note the applied map in the RCM does not fully cover the object)



Image three show that a new Red 'Diffuse' layer has been created. (note that there is only small section of the second Red diffuse layer showing).



I've tried all sorts of colour combinations in the 'Diffuse and Transparency' areas without success??!

The obvious solution would be to apply a 'transparency' map with a large background, therefore covering the whole sphere - but this would be impractical if you were wanting to apply a small 'logo' onto a very large object!! (The 'Transparency' map would have to be huge!)

Any help would be appreciated!!

By the way - my final goal is to apply a 'decal' image (like a company logo) onto a 'Diffuse' map image (like carbon fibre) - I hope this will be possible???!

Hmm, I'm a little confused. Best you use a b&w transparency map to control the visibility of a layer and don't use the diffuse color for transparency. It will works. Here a test from a few days ago.



For your first image try this: create a full black square image (f.ex. 100x100) and use it at the transparency map with the same mapping and tiling like the texture in the diffuse slot. Set the transparency color white - the whole object is transparent, but the textured area is not transparent covered from the decal is not transparent. Now, set a second diffuse layer behind the first diffuse layer. This is the basic material for the sphere.

Sorry, no time at the moment to post more now. I will create a tutorial for that.

I also stumbled across a mistake of mine yesterday that may help explain part of this issue. It turns out that the texture preview is not actually showing the whole plane - so that may explain why its not taking up the amount of space your expecting it to. It also explains why Micha had previously posted having problems with maps being cutoff even though no tiling or anything was applied. I apologize for the problems I'm sure this has caused...

Hi Micha.
My second image may be a little confusing as it shows a transparency map as a colour - This is not the case, I have used a black & white image but the preview only shows a 'pink' image because of the 'preview bug' reported recently.

I don't quite understand what you meant by

and don't use the diffuse color for transparency

I thought we have to put the 'main' image in the 'Diffuse' colour slot and the corresponding 'alpha' image in the 'Transparency' slot?? Is that not the case??

cheers

PS - what you've shown in your images is exactly what I want to achieve (ie one map on top of another) - Any thoughts on when the tutorial will be available??

You must set the transparency color of the decal layer white. All surface without decal around the decal map area is controled by the transparency color - white = transparent.
