Hi, what’s your exposure values on that interior shot? What are you using as your secondary GI solver, also have you tried rendering the inner-shot with some interior lighting?
Preferably, you would want an exposure ranging from 0-1 for your interior shots, I would start by introducing some proper interior lighting, lower that EV significantly and try this with a global material override to at least rule out any other issues. Once you are happy with the lighting, then remove the global override and see if the timings have improved.
As a side note, are you using HDRI+Sun for your overall lighting?
I think you should investigate what is wrong with your scene that it can’t render without artificial lighting. It’s possible that your setup is incorrect and if you don’t figure this out, next time you may do the same mistake again. If you can’t find the cause of the issue on your own, then perhaps ask if someone from the support team would be willing to take a look at your scene and see if there’s obvious flaws. Don’t leave it like this, because you won’t learn anything from that.
I was really thinking about, because I was sure it was some issues with the blocks, then I deleted the house, so all the blocks were visible at the scene, with the exterior light on everything it ran too fast.
I never had a problem like this one before, just to change de GI, or delete sobre block and it was solved.
Now I set the image to 2000px, and the image which was ready around 5 min when with 600px, now it’s been five hours and continue s like this.
Everytime I run the render, independent of the scene, I have this warning, thats why 3dsmax has the highest priority on my system.
Do you have some advice in this case? Or Do I need to go to 32 gb?
I have already done a scene of a gym with 62 different blocks, and was so easy to render. This one is killing my mind to understand what is the problem.
Next time you’ll get extremely slow render, open task manager and look at CPU and disk usage. If disk usage is 100% and CPU usage is very low, then you’ll know that your system has ran out of RAM. In that case, your only option is to stop the render and try to simplify the scene and/or lower render resolution.
That would definitely help, 32 GB is considered bare minimum for rendering these days. I myself have only 16 GB like you do, but i don’t render anything more complex than simple product shots and rarely go beyond scrren resolution.
Geometry takes much less RAM than big textures or high resolution render output. If you can’t fit your scene into available RAM, consider lowering resolution of your textures, check if they are saved with optimal bit depth and channel number. Render at lowest resolution that you can, delete all unnecessary render elements, consider turning off lightmix if you’re absolutely not needing it. Turn off displacement, or lower its settings. There’s plenty of things you can do to save a little bit extra. One thing is for sure - you don’t want to run out of RAM, otherwise your render will never finish.
I deleted all the exterior blocks, and just left the interior scenes. The render 2K was finished at 10 min.
I guess some block of the exterior was killing my RAM.
Thank you all for the answers, I learned a lot with you guys.
I still don’t know why the exterior render was going well, and how it could affect my interior render, but now I’m saved. Finally my client won’t give up! haha
