Multiple camera mapping in Maya
I have a question about camera mapping in Maya.
How could I make one shader with differents textures projected each one from a different camera ? I mean if I have pictures of a place take from different angles, how can I project each pictures on a single geometry (because in Maya all single geometries have a single shader assigned)?
It will be great to add freedom of movement (I am looking for a complet turnaround for exemple wich is impossible with one single camera-mapped picture I think :) )

Thx, it's a cool thread but the only think I have learned is that nobody have a concret solution :D JFrancis spoke about UVSETS but there is no much informations about it :cry:
I have found mental ray cam mapped stuff here but I would like to do the same with maya software:

Cant you get round this by using a layered shader? Then you can have as many projections as you like. Although Ive never tried it I believe you just have to paint alphas to blend between the projections - which makes perfect sense.

A layered shader or layered texture works just fine.

I am playing with layered shaders but I am not totally happy with it :) I dont see what areas of my projected textures I need to mask to have a nice blend. I just adjust the overall transparency between my two layered textures wich makes a simple switch between the two projections. If anybody have already experienced with this and could help me to fix it, it will be great :D

Thanks in advance

You can map that transparency swatch with an image file containing your nice blended alpha.

When using a layered shader in Maya for multi-camera projections how do you determine which layer of the layered texture shader that each projection camera uses?

Edit: Rather how do you tell Maya to determine which layer to use from the layered texture shader?

maybe of topic, but a good software for projections is Mari...

Hey All I just posted an article "Basic Maya Multi Projection Setup for Matte Painting"
You can download the working files to see how the shader is set up.
Can you tell how I feel about Maya projections?
