Hi,

I would like to use the logo I’ve attached on a 3ds max model, but the white part turns grey, and the transparent part turns white? What am I missing. Im just adding the logo with a UVW Map.

OK, couldnt attach a .tif file. Anyway it is a white logo, and inbetween there are some transparent parts.

Since I’m on a roll, I’ll fire up another noob question, when you add a logo like this with UVW Map, how can i keep another base color? (multi/Sub-object or composite ore something else?)

MAX 2010

ok, forget about that last part. I figured it out ( the base color part )

MAX 2010

Here is a simple example of what I’m trying to explain.

The renderd picture has grey letters on a white background, im aiming at white letters on a transparent background, like in the viewport to the right.

The colour is likely to be the lighting - or lack of it. You can compensate for that by increasing the Self Illumination of the logo material.

A Composite Material is probably the easiest way to get the logo onto the base material - you’ll probably need a separate Opacity Map - the same image with the logo full white and the transparent area fully black. You may be able to use the same image if it’s black & white anyway.

The other issue is that the logo is appearing on all sides of the object. To fix that you’ll probably need a Multi SubObject Material with the same background in 5 of the slots and the Composite (which already contains the background) in the 6th one.

To attach a file which won’t attach directly, simply zip it first

You haven’t stated which version of Max you’re using - this can be important. I would put that, and your brief system specs, in your sig - that way you can’t forget and we don’t have to ask.

Attached scene is Max 9 and includes the Opacity Map. The other bitmap (bricks) is part of a normal Max install (IIRC).

You can put your image map in the transparency slot of your material but the black makes the entire object transparent.
There must be a way around this but I’m drawing a blank right now.
Whoops, sorry, should have refreshed the screen before posting.
Ok, that’s right, a Composite Material type, I was using a Standard type
with mask in the opacity slot so the object was being masked.
Thanks, Steve.

Nice!!!!

This is just what I’m looking for!

I have a blog that explains the theory behind opacity on maps.  Check it out, it may help you out.

This is a great thread as I need to do this once in a while. I don’t work with composite materials much.  I’ve got this working with the logo the same size as the object and I only need it about 25% of the size and centered. My question is how do I control the size and position of the composite material?

I can’t remember what I did last week let alone last October :P

At a guess you need to turn off tiling (for the logo material) and use the Crop/Place to centralise it on the object.

Kind of like this thread, but with no tiling and use the Place instead of the Crop. I think ;)

Two things. When I turn off tiling I lose the colors in my logo. And if I’m understanding you correctly I don’t think my logo needs to be cropped, just reduced in size.

Use Place instead of Crop - those options are next to each other with a Radio Button for each. Tiling should only affect the number of repetitions of the image - it shouldn’t affect the colour of it at all. Try leaving the Tiling at 1 (in each direction) instead of turning it off.

I don’t have Max in front of me, so I’m working from memory (not a good idea, generally).
