Please add surface picking for instances too. Thanks !

I am going to review the plugin update code to try to avoid the full recompilation of the scene if it is not needed, in the IPR or in the "update scene" mode rendering. I am not sure what is possible, but I am sure that there is room to improve it.

Thanks!

Yes, the plugin can avoid the objects unseen by camera in the picking process. I will add this feature for the next release.

Thanks Juanjo that would be awesome

Some scenes with lots of instances of "heavier" objects have long updating scene in GPU phase, when rendering sequences sometimes this phase is as long as rendering phase. (30 seconds each ) This is a waste of time in animations where only camera is moving and instances are always the same. There should be some kind of a switch which would tell Octane to process instances only once at the beginning and update only camera on all subsequent frames.

I have a new test build with a complete rewritten update functions. In my testes with complex scenes with a lot of instances it is sometimes 100 times faster updating GPUs while rendering sequences in "update" mode. But perhaps something is broken ... we should test this build carefully:

There is a new code analyzing the scene changes that perhaps could break some kind of animations. And I need to test the network rendering to know how the render nodes are updating the scenes.

Let me know how it works with your heavier scenes, or your scenes with a lot of instances.

Juanjo, you haven't commented on my detailed post about my idea that you asked for, it's here:
http://render.otoy.com/forum/viewtopic. ... 80#p204782

I'm afraid you have just been too busy with this instance/large scene problem which of course is more important, no doubt. But just in case you didn't notice my reply, it is there

Somebody said it is impossible in polygon-based renderers but Octane and its LW plugin do many things that I didn't think was possible so I'm still hoping until you say it is not possible

Thank you very much and sorry for me being impatient

Yes, sorry ... I was thinking about your problem. Really I don't know a way to get this effect in Octane from the renderer point of view, but perhaps could be possible with the right displacement/opacity maps.

The idea is to have a displacement map with 0 displacement in the outside of the leaf (black, if you are using a displacement without shift), and an opacity map with the border expanded 1 or 2 pixels over the the border of the displacement. With this opacity map a little bigger than the displacement map, you could render a closed border in your object ... perhaps with little artifacts, but the render could be fine.

Would it also work if items are set to 100% Dissolve?

Ok, that I was afraid of but now I believe it is impossible so I won't dream about it anymore

WOW that sounds like a great idea! It could actually work, of course making such opacity map is quite a job but maybe it can even be made with ImageMagick so it could be automated.
I will look into this, thank you very much!

I was explaining to my partner what an 'Uber Developer' means.. hope you don't mind using you as an example.

Thanks heaps Juanjo looking forward to the next release.
