Baked Environment lighting for moving objects

I think the biggest problem with your technique are numbers of textures or texture size and as i see this, for being able to interpolate between different Z value, we would need to sample those textures/texture twice in the shader.

no, look,

@blenderaptor

20 levels : Z even number on the left, Z odd number on the right . Each square is a x,y plane, 20 planes from 0 to 19 meters high

The material i created has 1 foot on the left and 1 foot on the right. I don’t remember how the material works exactly but it’s about working like some modulo system with a smooth progressive move from bottom to top

@SoundDifferent

Or what if character can throw something in the window? What and how we would sample if we throw an object into non walkable area

Thats why i think the more easy stuff is to rely on a big large rectangular texture that covers the whole map .Up to the game maker to make a map that doesn’t waste space

@SoundDifferent

We sample a UV coordinate of those mesh by raycast and sample the texture where we store the approximate light in those area where we are.

We tried something like that before : it was about finding the closest vertex from the ray hit point on a baked floor texture. Problem with this , is that, a tiny little variation in the information in the vertex makes your WHOLE (not a point shader like in materials) character twinkle like a star. And everyone knows how much noise there’s in a baked texture. Horrible ! Ofc, it’s possible to use fake floor with high blurred texture

So after that, i tried with a light probe system. Storing information into a matrix after vertex color baking

My progress for a baked Light Probe system for moving objects in Range engine :D

As you know, Bge, Upbge, Range has that problem that there’s no real indirect lighting … so unless you full your scenes with tons of lamp ( with all the light bleeding it can causes and the severe harm it does on your fps) … your scene will be pretty dull and ugly (get only a single sun as light source to see how ugly your game will look like) . Ofc you can change the shadow color for not having it completely black and so it will be less harsh , but the problem remains : it looks so flat. A…

But just like with the Ray stuff … it applies to the whole mesh … so it’s not good, pixel-point in Materials is far superior

So, at the end of the day, if i combine what i’ve done in the other thread with the stuff here, i think it would be pretty neat … just have to accept that the map gonna have to be limited in the X,Y space and not too many “Z floors”
