<div dir="ltr"><div>2) someone else will have to chime in about color space stuff. Reflection probes will be needed, maybe call that 2b for this conversation. Simpler 2a would be image-based lighting from a single global source. Fake it til we make it. Or til we can fake it better, since we're talking reflection probes and not ray tracing.<br></div><div><br></div>3) glTF perhaps? Blender could export the node tree as long as the set of supported nodes on the other end (game engine) are known. Or combine those into text-based GLSL, which glTF can handle.</div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature">Mike Erwin<br>musician, naturalist, pixel pusher, hacker extraordinaire</div></div>

I'm pretty sure that Unreal users have asked this a lot. Is there anything planned on the way of doing a PBR worfklow? (more in the vein of Substance Painter). Game engines are almost standardized on that nowadays so going from them to blender and using PBR is kind of difficult..<div><br></div><div><br></div><div>Juan</div><div><br></div></div>
