Same settings different results
Same settings different results
Hi guys .
I have a question ... Why do i get different results from a scene ( with the same settings ,lights , camera ,geometry etc.etc .) if i change the rendering mode?
If i use CPU+GPU i get darker joints and brighter renderings...Is that normal? In some cases the dark joints seem to be a bad modeling problem.
Everything is fine only with CPU.
Thx in advance.

Re: Same settings different results
Yes, I reported a quite similar issue back in 4.0.15 to the devs, I tested the example scene I provided back in the day and can reproduce the problem:
In your case you only render with the Titan X card, no CPU involved hereLal-O wrote:If i use CPU+GPU...

While it's weird that the brighness is different, I kinda like the GPU render better.Lal-O wrote:Hi guys .

GPU makes everything better!Oscar J wrote:While it's weird that the brighness is different, I kinda like the GPU render better.
Re: Same settings different results
Yeah but as long as i know the goal of using both (CPU+GPU) is getting faster rendering times, right? Most of times my deadlines are really short so i think that disabling any of them is not an option to me ....just a toughtZom-B wrote:Yes, I reported a quite similar issue back in 4.0.15 to the devs, I tested the example scene I provided back in the day and can reproduce the problem:

Here is another example of a " bug " in the joints with CPU+GPU
I can deal with brightness variation in the images, but the "light" through some joints i think is a problem

Re: Same settings different results
Does look like some sort of precision issue.
Re: Same settings different results
Maybe obcjects have their origin far from geometry?
Re: Same settings different results
Yes it does look like, but the model is really well done, i can assure you thatOscar J wrote:Does look like some sort of precision issue.

Re: Same settings different results
Yeah I meant an Indigo precision issue.
Re: Same settings different results
Does adding floor cap at the bottom fix it?

Ooooohh i see... Yes , it seems soOscar J wrote:Yeah I meant an Indigo precision issue.
Re: Same settings different results
I tried with and without the floor cap and no luck. Only CPU and problem solvedEneen wrote:Does adding floor cap at the bottom fix it?
Re: Same settings different results
still you are not rendering with you CPU in GPU mode mate, believe me!Lal-O wrote:Yeah but as long as i know the goal of using both (CPU+GPU) is getting faster rendering times, right?

You have no openCL drivers for your CPU installed, otherwise your CPU would be in the OpenCL device list, doublecheck CPU usage during rendering when your Titan card is active and you'll see!
It should look more like that:

Re: Same settings different results
Maybe you could copy these few elements in a new scene and upload it, so the devs have some reduced scene to test while fixing itLal-O wrote:I tried with and without the floor cap and no luck. Only CPU and problem solved

Re: Same settings different results
OH MY GOD!!!... I've been living a lie!!!...I've always thought that by simply checking on the OPENCL feature i was able to render with CPU and GPU at same time.

Would you please tell me what do i need to do to get my CPU shows up in the device selection? Is an Intel I7 5960X. I would really apreciate your help
