Hi Nik

Great script.

It would be awesome if you could batch add a corona color correct to all diffuse channels in the object or multi map (or other channels such as reflection, translucency etc). This would work in well with Corona's new color correct "take settings from map" function.

Cheers

This looks like what I'm facing;

But there's no "slow caustics" in my scene and the msi is 20

Ok so sorry I haven't been responsive, I've been swamped.

Putting the MSI back to 1.0 did clean up the noise although it's hardly ideal either. The only way I could solve this was to load a scene from before I started to mess with the dev settings and save out a preset and then load the preset.

I'm sticking to the original hypothesis that something I changed in the dev settings while experimenting with pool caustics baked into the render settings.

Let me know if you'd still like me to upload a scene, I faced this problem on all scenes not just that one. I'd wager that I could save out a render preset and you could apply it to any scene and it would generate the same white pixels.

Oh and it doesn't matter about the geometry, I remade the glass panes in max and it still happened.

Nah, first thing I tried. The only thing that fixes it is to add a rayswitch to the material and push the reflection glossiness in the material applied to the GI channel to 0.0.

Hardly something you want to do for every glassy material.

Thanks Maru

My bad, I upgraded to the wrong version, I now have the latest version installed and it hasn't fixed the problem.

Upon further investigation, I think it's a caustics problem (the standard kind, not the slow kind).

White dots_01 shows the effect on the beauty pass. white dots_02 shows the gi pass and the weird tiny caustic effect happening on a material in the scene that has glossiness at 1.0. White dots_03 shows the effect clearing up when I add the material to a rayswitch with the GI glossiness set to 0.0.

I was messing around the other day trying to to pool caustics using the tools in the dev mode. Somehow I think I must have changed some settings that have reflected on my caustic settings even after I have switched the render engine back from PPM to progressive. I have uninstalled and reinstalled Corona numerous times and merged this scene into a fresh scene and created the render settings from scratch (without messing with the dev tools) but still the problem remains.

Any way I can reset these to default values?

Cheers

Hi

I'm using Corona version: 2 (Release Candidate 4) and for the first time ever, I've noticed that my glass windows (well, anything with reflection glossiness at 1.0) are generating white dots (tiny fireflies) in the indirect lighting. This in turn is visible in the beauty pass.

I'm using a model exported from revit, it's the first time I've used models from this particular client, everything has been re-textured etc though.

Anyone seen or solved this yet?

Cheers
