Strange artifacts/issues offscreen rendering of shaders.

[ddutchie]

Hello Vatara.

I'm trying to get a runtime-tilable-texture camera up and running on an iphone using some crafty tricks and scripts i have gathered over the last two months.

As I've mentioned I am working on a mobile texture tool, but thus far I have been running conversions on the cpu. (I will be reworking the project to combine your shader based approach with what I have so far.)

Anyway. Issues and artefacts appear when I'm trying to generate my tileable texture.

it works like so.

There is a GUI camera
There is a rendertexture camera, set to aspect of 1:1 (square)
There is a webcamtexture.

All I'm getting from my render texture is this glitchymess,

Which does its joB, but It does not render an image on my phone.

Let me know if you would like to take a look

I meant to post this image last.

To show that it does try to read the right pixels

Here is what I came up with yesterday after exploring your code.
