Rendering is the bane of every 3D artist’s existence. In this video, Grant Wilk looks at a few ways that you can make rendering a bit easier on yourself!

Switching from CPU to GPU is not a tip or trick. And of course it is not an optimization.
I personally don’t see any real tips here. You got speed up just by switching to GPU in 99%, but that’s all.
he actually talks about setting up the light paths values etc which can have a significant impact on speed
It truth, it does not makes much impact in most cases.
Hey Ivan!
I appreciate the feedback on this video (I’m the one in it, in case you didn’t know). This video was targeted toward absolute beginners, but I’ll try and keep a larger spectrum in mind for future videos. I’m always looking to improve :)
Cheers!
I think the problem is that when you see the title the expectations are that is going to be a video for experienced users to know how to improve cycles speed, and then you find that it is for absolute beginners, you should include some indicator that this is for beginners that don´t know cycles :)
But I like the production quality.
Cheers!
I agree ! Also, there is a lot of mis-information by giving random settings, that fit his scene, but not every scene.
This video is not a tips and tricks, but more of basic rendering setting for beginners.
Cool Tut. Great info. Now I know where to experiment with my settings without messing up the scene :) Renders will be a lot faster. And really professional Videorecording. I enjoy the professional sound of the vocalrecording.
Thumbs up!
Don’t let the nice audio drive your opinion, there is a lot of miss information on the video, starting at the gpu’s in computers. . . up to setting the max global bounces of the light path and then set also the transmission, that max/min (in blender trunk that min value its no longer there) set to 4 basically limits the other values, if that max bounces its set to 4 you can set Diffuse, glossy, transmission to 50 and Cycles will use only four bounces of each, because of that max value clamping.
And probably the most important part to control noise vs time in Cycles, where a real render time difference can be done, wasn’t mentioned at all, Sampling.
I wouldn’t comment on these kind of tutorials but CG Cookie its an important name, weird to see this kind of content with its seal.
Hey Nahuel!
I appreciate the feedback on this video (I’m the one in it, in case you didn’t know). You’re absolutely correct in this assessment. The global bounce issue was a mistake made while recording that slipped passed me during the edit. I appreciate you bringing attention to this issue. I’ll do my best to make sure future videos don’t contain errors like this.
Cheers!
Here’s my tip for a significant rendering speed increase in Blender: try Radeon ProRender. It’s free and fast, particularly if you’ve got a somewhat recent AMD GPU. At the time I write this, it still lacks some features, such as vertex color support, but its development progresses swiftly.
