ShadowGenerator render manually and don't update

[KevinBLT]

Hello everyone,

 

I'm back again with a question.

I have a scene (see screenshot below) that is static after the construction has finished.

I want to render shadow once after the construction. I tried "renderTargets" off. But the shadow sometimes disappears.

 

I would need something like a shadowgenerator manual mode.

So like "calculateShadow" and then it keeps this shadow map until the next "calculateShadow" call.

 

Is there something like that or an easy way to achieve that?

I think this is something useful for other users too.

 

 

Have a nice day,

 

Kevin

If the light isn't moving and mesh isn't changing, you can just bake the lighting into a light map using blender.

 

What would be awesome is if babylon had a lightmap baker built in - was looking for a javascript implementation to copy but I couldn't find one

The Mesh changes.

But only if you change the settings of the construction.

Then all the bar positions get recalculated.

 

But between then and the next change nothing happens to the view, except the camera angle/zoom.

So these "buildings" have neither seen blender in any time nor will they see it in the future. 

It's completely build out of "BABYLON.Mesh.CreateBox" and CSG subtractions.

 

I hope it's a bit clearer now.

We have exactly what you need:)

 

http://doc.babylonjs.com/classes/2.1/RenderTargetTexture#refreshrate-number

 

​

Use 0 to render just once, 1 to render on every frame, 2 to render every two frames and so on...

 

So set shadowGenerator.getShadowMap().refreshRate = 0 and you're done

Oh and btw I used the function linking feature of the doc which works perfectly (GG @temechon:))

Thanks :)

Hello,

 

I am back from my holidays. I will implement this !

 

A big thank you. Now I can use the biggest possible shadow map, I think.

And everything will look fantastic.

 

 

Have a nice day
