environment transformation

Hi,
I was wondering if it was possible to arbitrarily rotate the environment texture (in the rendertarget). It looks like the heading and pitch offset the texture along the virtual environment sphere's uv, and specifically the pitch causes pinching at the poles. What if I want to rotate the entire sphere on its side. How would that be done?

Thanks

I'm testing the transformations inside the environment node, that is using a spherical projection in this case, and I think that the current behavior is the only one available. As you say the heading and pitch parameters are transforming the projection UVs. I'll investigate if other types of projections or transformations are possible.

Thanks,

So I've done the same and got it to work by going inside the target node and attaching a spherical projection node to EnviroTexture and another transform3d to the projection and it works nicely. I think it should be implemented in the rendertarget asset and exposed to the user. It's a much more desirable behavior for tweaking the environment.

Thanks!

Ah, Ok. So you are linking the transform_3d node to the spherical projection node, not to the texture node, right?

Using this workflow the environment transformation seems to work fine. I can modify the render target HDA to work with this node setup, at least as an option.

Thanks for investigating this issue!
