Chaos Corona for Blender / Re: corona 3 crashed

« on: 2019-09-05, 14:35:03 »

Sanekum after I deleted my render passes and rendered I had a white screen in Corona. When I clicked add render pass and tried to render it would not render. I have found 2 emiission materials. Should I delete them? I am still trying to find out what objects they are on. Do I need to switch to cycles and render and for how long if I do? Does that create a render pass. I am new to this. Thanks

Ok so I downloaded chocofur file and Scene file didn't work for me too, but I never use them anyway
Second I've deleted render passes, they were created with older version of blender plugin and doesn't work with latets, just delete all
Set Overwrite geometry to All
Check those lamp over stove, they are using emission material with IES attached, check path for this IES in material setting, IES file is in the Chocofur\maps folder, make shure path is correct

What do you mean check ies lights. Where do you check ies lights? Do you do an "ies" search? How do you tell if profiles are missing? What is a profile and how do you create it? What do you do? I am new to this. Thanks

Error on your printscreen says that Corona can't read IES profile
Find emission materials in your scene and check path to IES files

Here is the error report when I tried to load the scene file.

Check your passes settings, delete all and create new if needed

and check IES lamps, maybe profiles are missing

There is a lot of big players jumped on the 2.80 hype train, Octane free tier(it's buggy now but damn fast), Redshift, Vray and Arnold are coming too
With awesome Corona devs and our champ Blanchg I think blender addon is in the right hands

Hello.
Can you help?
Set the corona 1.6.3 on blender 2.79
I try the addon version 8.0.35 and 8.0.49
Blender sees the corona. The countdown of the demo version began
When I click on the render, the calculation begins and ends in a second. No messages or errors are reported.

Does Crorona 3 works?
Whats written in console?
It is a new file or not?

Standalone 3 is awesome, is there any chance that we will get caustic in the future? maybe in Standalone 4? :)

@blanchg thank you as always, no hurry.

@Sanekum your testing data are very helpful to optimize ram. I'll try the children menu.

I am glad to help, if you need to make realy large scene with aerial view or similar and suffer from Ram overload you can also use trick with single proxy and MultiShader material
For example it's all one single proxy tree instanced by particle system, I haven't worked very much with this feature yet, but it can give good results with more tweaking

And it works not only for trees, I made car paint material with it

@Sanekum Yes, the "ground plane disable" bug shows up in some cases, but not in other cases. Hard to pinpoint the exact cause to find a definitive solution.

In your "1 proxy tree 100000 instance total 1487mb Ram" example, did you Alt+D to create the 100 children (=100 instances), then group the 100 instances as a unit for particle emission?

No I didn't duplicate anything, all instancing are made by particle system only, from one proxy object, and for the children I use Children menu
Very powerfull featureif you need massive amount of particles

I made test with group of 100 proxy duplicates as you mention and there is no difference in Ram usage

Main thing that is the more particles you have the more time it takes to export, even with proxy, and number of particles encrease file size
1000 particles with 500 childrens gives total 500000 particles and about 13mb for my blend file, but 500000 emission number without childrens gives 220mb blend file

@Sanekum Thanks!   Is your "duplicate ground mesh" workaround able to render a relatively large vegetation scene like 300m x 300m full of plants, without hardware overload?

I make small test and noticed one thing, in my files emitter is renderable, but I'm pretty shure that had same issue as you some times when I create grass, gonna figure out

I made landscape 1x1km and add particle system with group of 8 different trees, each one of them is about 500k-1mln tris

Main hardware overload is not from how many proxys you are using, but how many of them are unique
8 different proxy tree 100000 instance total eats 3993mb Ram
8 different proxy tree 10000 instance total eats 3882mb Ram
1 proxy tree 100000 instance total 1487mb Ram

@blanchg  when I try to use proxy with the particle system, I encountered this strange problem. The plane renders correct when it's used just as a plane, but when I use the plane to scatter objects with a ParticleSystem modifier, it renders all black.

Blend file attached for your investigation, I have replaced the external proxy with a simple cube, because I don't know how to embed the proxy in the blend file, but the problem is the same with a cube as with an external proxy. BTW, thank you 3000 for your work on this wonderful addon.

Plane is not black, it's just disabled for rendering as an emitter.
For Cycles there is a button, but in the Corona it does not work

As a workaround for grass fields etc. I just duplicate ground mesh without particle system
