Note, this version supports now officially GTX10XX graphic cards, although the related Presto build is not yet fully optimized for them.
This is why, the version ships with 2 Presto libraries and, by default, Thea will pick automatically the best fit one, depending on your graphic cards.

As always, enjoy rendering!

Best wishes

Great fixes, thats always nice. Is it possible to explain them in more "regular people" language Some of them i dont really understand or what it does.

for example, whats does this mean, "Added user mask channel support. (Channels)". I cant find it and mash id was already there. I dont get whats added then???

Could we have a fesnel ramp which has better and more control. I mean this fresnel ramp doesnt seem todo anything when you use something else then default settings. I would like to use a better working gradient for the fallow, also perhaps on the IOR value.

Thank you all

Yep, I will not argue here, the fixes are rather very quick explanations that even developers may sometime refer to the actual code changes to remind themselves what has changed!

for example, whats does this mean, "Added user mask channel support. (Channels)". I cant find it and mash id was already there. I dont get whats added then???

That was something needed for Cinema4D, since the mask channels were being indicated with their sorted number, assigned automatically by Thea. Now, they can be referenced with their original (unsorted) user-defined index.

First of all, Fresnel ramp needs to be assigned to a component such as Diffuse, Reflectance, Translucent. It will not work on other layers such as Emitter or Layer Weight. The UI, as is, is indeed not that great for editing. I can't do something more for the time being.

Best regards

Okay, so its true i dont see any difference then? I mean i could already assign a number or index number to something. I dont see difference in studio with workflow.

But was is fixed then for using fresnel ramp on emitter if icant be used like that?
Having the fresnel ramp work on the layer weight would be great ass well. I saw quite some people who would digg this.

Ive got questiona bout saving img.thea file. Was there a option that is saved on rendertime. I think i remember that when thea is rendering and it crashes you could always revert to that temp saved img.thea file. I dont see a option for this and i see the file appear only when render is either done or stopped. When there is a crash there is no imgthea file.

I still have the option in both Studio and Thea4SU.

Do you see it beeing saved while rendering? Mine only appear when the thea stops rendering and get deleted on shutdown.

thanks for this.

hard to tell from the changelog so can i ask if there are any fixes or improvements for the Presto noise issue?
