I am wondering how to control a Bitmap size/tile so I can methodologically divide a bitmap to project each changed bitmap into a circular projection of projector lights to simulate an IBL light rig.
How do I make a way to modify bitmaps and have a bitmap output after a node modification?
Bitmap Control for Projector Light
Re: Bitmap Control for Projector Light
Perhaps this material can help as an example:
viewtopic.php?p=13872#p13872" onclick="window.open(this.href);return false;
Scale to your tile size and Move to the XY coordinates. Which is how I animated this texture. Actually you only need the DefaultTexCoordShader:

Re: Bitmap Control for Projector Light
Well that works fine for shaders..... But I'm specifically wanting to scale, tile and transform bitmap information... Like this node attached.
It takes the bitmap info from and InputBitmap, then changes it and spits the info out as a RGBout for a textureshader node. I would like to change the bitmap info and output it as bitmap info again.
I found a zoom composite node and a blur node that may do the trick! Haha! Thanks clinton, they are your compositing nodes that are doing the trick.

Hi trueBlue
With the regular projector light you can rotate the light around various axis and the image will follow, with projector2 the image stays put as you angle the light....is this correct behaviour?

Ah...I see. Looks like it will not work then. I removed the post. Thanks!Saul wrote:Hi trueBlue

Re: Bitmap Control for Projector Light
I found a way to fix this problem, and the solution is in my IBL or false GI light rig thread. I will soon release it for those who have decent video cards to try it out!
