Render shader to use it as texture in an another shader

[benjiGir]

Hello,

I'm making a realistic Sun using computed shader but i'm facing a little problem. I made a codesandbox of the concerned part https://codesandbox.io/s/goofy-currying-xb95r .

First, in the component SunTexture I use a cubeCamera to get the rendered shader as a texture.
Then the texture is passed to the component SunObject. In this component, the texture is used as a uniforms value, in this case uPerlin.

Both components rendered properly but the SunObject doesn't seem to render the way I expected. (I add Perf module to make debuging easier) When I console log information of the SunObject shader, the one containing uPerlin, I can see that the uPerlin value is as I expected, a cubeTexture.
So, SunObject should be seen orange-ish, as it is actually but with layer of noise that gives the sensation of boilling matter.

I'm sure there's a mistake with the render order or something like that but i really can't figure it out. If someone has an hint or an idea :).

Thanks in advance for any help.

Wow I got an illumination this morning. I solved my problem.

There wasn't any problem, just wrong size for the sphere geometry of SunTexture component. I reduce its size and magic !!! no my Sun looks like a boiling Helium star instead of a perfectly rounded apricot.

Hope my case can be useful for someone who's encounter the same problem.

Thanks for your amazing job.
Cheers.
