decal again

[Dave Buckley]

i have an arch and design material already setup.

 

i now want to add the company logo to only part of the model that contains this material.

 

any ideas?

 

the composite map doesn't seem to help me

One way is to use a blend material.

put the background material in slot 1 the decal in 2 plus a matt for the decal in the mix slot.

Now add two UVW Mapping modifiers to the stack changing the map chanel to 2 for the decal one then in the mix material point the decal bitmap also to map channel 2.

From my notes - hope they make sense:

Combing logos with Materials

 

01) make a multi-subobject with 2 slots - one for colour/base material and one for logo

02) IN THIS EXAMPLE, the base colour is an A&D Material - set the DIFFUSE LEVEL to 0.3 - lets the logo show through

03) COPY the material from the first slot to the second slot

04) In the 2nd slot, click on the MAP button next to Colour, load the logo graphic in, and set the channel to 2

05) in the stack of the object, put 2 UVW Mapping modifiers - first is logo (channel 2, planar), 2nd is base colour (channel 1)

06) Logo mapping is set to Planar

slight problem

 

the material on the object is actually a multi-sub object

 

in this there are 2 a&d materials

 

for example

 

shiny yellow material 1

rusty steel material 2

 

the logo needs to go on the shiny yellow.

You can use a blend material in a multi-sub material:

In the "shiny yellow" slot of the multi-sub, place a Blend.

Slot 2 of the Blend gets the "shiny yellow."

Slot 1 will get the material with the logo bitmap in the diffuse.

The mask slot will get the logo's mask.

Now you can control various reflection properties and such of the logo itself in a different manner than the "shiny yellow."

 

You could use just an A&D and a composite map in the diffuse, but you won't have that seperate control.

To do that, put a Composite map in the diffuse slot, make 2 layers. The lower layer will get just a color (go into the map button and use the color swatch) The upper layer will get the logo image and an alpha map for it.

i'm just a big nob (a massive one)

 

i had it right all along, it was working perfectly fine

 

the thing that wasn't working was the fact i was trying to position the decal with in the viewport but i couldn't see it, no matter what i did with UVW maps, tiling, alpha channels, composite maps etc etc etc

 

i forgot to push my little checkbox to show the map in the viewport.

 

ok you can all have a laugh now

we all forget the basics sometime . . . . don't we?

Too true. I sent a whole load of renderings last night and forgot to turn of the vray toon render from a previous test.

Boy was my face red this morning.
