ok that makes it clearer where the problem is … I’ll try to fix this as well.
I’d appreciate if you could create a repro of this on github to track this: thub.com/playcanvas/engine/issues
thanks!

I would probably do this:

  1. change the current camera that render the world to be at priority 1 (so it renders second)
  2. add a child camera to current camera, with the same perspective settings. Making it a child should make it have the same transformation. Call it BloomCamera, set its priority to 0 ( so it renders first), add a layer to it with objects you want bloomed. And set it up to render to a render target texture. And clear color to black on this camera.
  3. Attach bloom postprocessing to this BloomCamera - this should bloom only the object that you rendered to it.
  4. To your main camera set up some callback, for example on before UI layer gets rendered. This should additively blend the bloomed renderer target texture on top of already rendered framebuffer of the main camera.

It doesn’t work…

Try debug displaying it this way
app.renderTexture(-0.6, 0.7, 0.6, 0.3, texture);

It says that renderTexture is not a function.

Hi @Marks,

For that specific line you need to update it to:

app.drawTexture(-0.6, 0.7, 0.6, 0.3, texture);

Hi, Everyone, do we have a solution for this yet?

If so, any sample project? I would love to know.

Thanks in advance,

Hi @lenvanthis, not sure if there is a sample project. @mvaligursky given the latest updates to the PC engine, what’s the proposed way of doing this now?

I don’t believe there’s anything new since I responded to this last time on the forums, there are few topics discussing options around here.
