How to use maps made with CGeometry_NormalsGeometry?

[Sparkwire]

So I've made a render using the CGeometry_NormalsGeometry render element, however it doesnt act like any world space or object space normal map ive used before... how do i get use out of maps made with this feature?

My main use was rendering a picture of high poly to project to a lowpoly, preserving the perspective of the highpoly ( normal method of render to texture would make these details flat and unattractive)

So i can't directly make a normal map and can only use this render element.

Unless you're rendering on completely flat surface, you can't use NormalsGeometry RE for projecting high-poly details onto lowpoly mesh. Also, is there a reason why you choose NormalsGeometry instead of NormalsShading? The latter additionally would give you smoothing as well as bump map info.

SO there is no way to have a world space normal made out of a high poly without using render to texture?

I've gotten results like this but it doesnt work exactly the same way as i'd like it to



I want to take this picture, project it onto the lowpoly and then convert the baked world space to a tangent space.

Nope, you can't do that without RTT. Unfortunatelly, at this moment Corona does not support RTT in projection mode, which is needed to be able to transfer shading info from one mesh to another. But of course there are lots and lots other tools out there that does this job very well, it's only if you want to bake Corona lighting, you have no options for now.
