Rayscaper, My trip down the road to adjumacation.
-
Essentially the balance issues make it difficult for me to see where the illumination level is do I will have to render a scene or two with just the lamps I have made and adjust from there.
-
Weird this, one spotlight and one directional light along with the fake emitter surface.
I ramped up the directional light alone to 100.00 watts. OK, distance that this illumination appears at needs adjusting. I then reduce the power levels to zero watts and the illumination does not change. I will close Rayscaper and open it again, see what happens.
-
OK, part of the reasons for a simple black screen rather than a render is that for some reason, there were TWO 'ghost white' textures/colours imported. Only one of which had any reference to 'glass'.
Nice to find that.
Even at 200w the cone of light is not apparent from the now 2 x spotlights.
-
OK, the properties assigned to materials etc in Rayscaper are not surviving shutdown and restart on this pc. Memory? 32gig and a decent graphics card suggests not.
-
@Mike-Amos I believe there's issues when there's a mix of emission materials.
There's also some odd behaviour whereby an emission value will decide to not emit light until you reset it.
I'd wait for a fix around lights

Here a little scene to see the values I used to light scene:
watchmen-emit-scene_2020.skp
I'd be interested in your render times. This is 30s for me on GPU
-
With Sketchup v2022, instant crash, no bugsplat.

Just to point out that this is the old pc which is getting on a bit.

Hey @Mike-Amos
Some screenshots would be helpful to follow along!

Mike, can you reproduce this consistently? If so, I'd like to check it out with your scene on my computer.

Do you mind posting a screenshot of what you mean by ghost textures?

I wouldn't blame your PC
Rayscaper is still beta, so bugs are possible!As @Rich-O-Brien pointed out, there is some odd behavior with lights. He reported it earlier, and requires a fix. Lights should behave better on CPU, but yeah wait times are a lot longer...
Tried again. Rendered but took 17m 31 for this.
Is this @Rich-O-Brien 's scene or yours? Do you mind mailing me the scene thomas@rayscaper.com?
Cheers,

No, does not reproduce, random over several renders.

Ghost textures, where the same texture is apparent more than once in the materials list. Ghost white is a colour I use exclusively for glass. If as in this instance, the light fitting is imported, the material is listed twice or more and treated as a seperate instance. Only one of which had a glass setting.
2a. I believe this is a bug where imported models have the same material as the main model. The model (Light) itself is probably unrealistic so I will adjust and try again.
- This is the scene Rich posted. I am going to recheck this over the weekend, possibly another example of imported models not being assigned a mat finish or possibly not surviving a save of the file.
-
-
As I thought, the scene as opened is a blank canvas. All mats are 100% opaque and no emiters.
-
Made mat 003 an emiter and this ran over 4m 20s.
There are lines here not apparent in the render window, geometry? Yep, when I selected the view Rich set the geometry (Hidden lines etc) was switched on by Sketchup. Old bug.
-
An observation, I looked at mat 003 and emission which I set to colour, had been switched OFF. I did not shut the render window this time round.
I shut the render window because I cannot minimise it without minimising Sketchup first, it would be nice to be able to minimise Rayscaper independantly.
This scene just rendered at 3m 42s with emision set to colour and power at 1.00.

That sucks, will keep an eye out for this.

Could you send the latest iteration of your scene? It will help me better understand why the material is listed twice.

I'm not following on this one, can you provide a small test scene? Or instructions to reproduce so I can understand the expected behavior?

Apologies, but not following which scene you are talking about.

Which lines in the model, I have it open here but I'm not sure I understand:

Is this the behavior you are referring to?
If so, yes that is annoying and is new to me. I will put it on my list.

@Mike-Amos - Something I learned from @Rich-O-Brien. There's a great tool called ShareX (https://getsharex.com/). You can use it to quickly capture and annotate screenshots. A screenshots with an arrow, circle or other annotation immediately helps me understand what the problem is. Text is harder for me to dissect issues with Rayscaper.

I am going to have a look at that but it seems most of the problems are based around lost settings for colour/texture/material between openings of Rayscaper.
The issue of Rayscaper not minimising is nothing new for me here.
The led lights in the kistchen of the my home renders was due to the glass cover of the unit becoming opaque. No way light gets through that. and later render has demonstrated this by castnig a shadow of the light fixture.
I believe this is nothing serious and only a matter of time. I know you are getting this right mate. Thanks for making this soon to be great program.

Thanks for reporting. If there are easy-to-reproduce examples, please send them my way. I appreciate the help.

I appreciate your support, Mike!

@pixelcruncher Moving on a bit.
I have noted that textures that are repeated as in the wood texture on the furniture, can become corrup. the scaling can be lost but sampling from a different piece of that furniture can fix the issue. It's not apparent here for example.
The 'chilli cat' image here has rescaled too. Originally stretched is has reduced in size in the render.
