yeah the depthmap is 16bit so it doesn't have enough values

the best I can do is get the actual faces of the 3d model. i.e. super low poly, and I can't access the phong smoothing.
C3 has access to it of course. So the shader, even though it SORT of can use actual normals from depth, looks really low-poly and not smooth. I'm tired

oh interesting! dFdx/ dFdy and depth map?

Making a matcap shader for Construct 3, now that it can import 3D obj
Since we have no access to normal maps, I bake a normal map and load it as a texture. Shader has access to it, so it can use the normals as input to do the matcap shader.
I encode a 64x64 matcap texture in the shader itself.

yay!! and I just made a matcap shader that finally works!

thank you. I do pixelart, not injections ^-^

do these only see 4 directions? do they see slopes? Do they blend, for cylinders? Amazing work!

they're sick af indeed!!

oh wow. maybe that's a feature we could ask Ashley to make available? Or even better: normals.

I guess you can't? but if you can, yay! For now I have a great fake chrome and a very real gouraud/ sand effect

yes, it works great. Have you gotten the sand shader to work? It needs a .glb with a baked normal map , for texture

ha! setting 3D rendering on makes clipping disappear!

you're way more skilled than I am! that's as far as I go :/

you're right! The issues with 3D direct rendering are:
1. you can't do pixel sampling/ blur effects, because the compositor doesn't create an intermediate texture
2. c3 might STILL add a pre-draw step, so it's not guaranteed?
But it seems more suitable for 3D

Yeah! Do you have time to submit a bug report?
