hi, im currently using gdev with 3d but i been wanting to get back to c3 and use this addon to make a 3d game but no 3d lighting kept me back. now i see it has one, should i switch over now? or wait a bit longer? is it stable? does it cast shadows?(im guessing not) how would it do lighting up a room or hallway? like would a lamp source be able to light up a whole room or do i have to use multiple lights per face of a wall. how expensive is it lighting up only walls or things that dont move at all? 

a little test demo game of walking around a room or house showing off the lighting would be nice on this page. perhaps with that model testing animations you currently have, in the middle of the room or something.

I am going to say wait, this is the very first experimental iteration, lots of optimization and experiments to go. It is also per face lighting, not per fragment or even per vertex. CPU is pretty heavy for dynamic lighting.

You can mix and match point lights and spot lights.

I think a possible end game is good, fast baked lighting for static 3DObjects, a minimum number of dynamic objects and lights and something cool will be possible, when we get there. No shadows / occlusion.

If you are interested in helping experiment go ahead and jump in, but again still in experimental mode and not all experiments work out!

webGPU also helps with baked lighting performance, due a C3 renderer change, but webGPU is not available for C3 export yet.

ok cool, ill wait til june before i renew my sub to construct 3. maybe some cool changes by then. ty!

You are welcome, we'll watch for you in the Summer.
