Is there a way to convert the RGBA type into a texture as when using the texture sampler

it converts the 2d texture into a rgba and we cant use that data for texture data in material editor.

Hi Kavin,

You can import your texture using the Texture 2D Object Parameter node which exposes the texture as a Texture 2D object. However, once you've converted to an RGBA value, there is no way to convert that value back to a Texture 2D. (If you think about it, doing this wouldn't really be possible, since you're only calculating the value for one pixel and all the other pixel's values aren't available yet). You can actually work around this for most situations though by calculating the values for other pixels and passing them around as RGBA instead of Texture 2d.

If you still need help with a specific problem, let me know and I'll be happy to help you find a workaround.

I have a question.
What do you think about sampling the color processed by "Texture 2D Object Parameter" again?

Should I use "RenderTarget" or some stuff?

I have solved it on my own.
Had to use Render Target though...

Thank you🙏
