![]() ![]() Yes, I'm actually thinking to do a comparison test, which for me means start learning first, and then compare. noise-free, no indirect lighting motion-blur etc. I think you could start by defining the exact criteria of your needs for motion graphics in terms of the visual qualities. MartybNz verysame Now, if (and considered my lack of knowledge for me it's a big if) this is the case, and simple scenes is not where Mantra shines in terms of speed, I'm wondering what would stop SideFx to address this situation (and hopefully they will do). Now, if (and considered my lack of knowledge for me it's a big if) this is the case, and simple scenes is not where Mantra shines in terms of speed, I'm wondering what would stop SideFx to address this situation (and hopefully they will do). From what I'm hearing, though, it seems it is true the former, and Mantra just gives its best when it comes to bake crazy amount of data. I didn't get to the point where I know Mantra to such a level that would allow me to know whether simple scenes require longer times than expected because it is just the way Mantra works or because I didn't tweak the proper settings. ![]() But of course the same remains true if I need to render simple scenes, which actually happens more often than one would imagine (because it's a fast turnaround, or maybe what is needed it's just a proof of concept or simply because client needs plain, clean scenes). What's working great for my needs right now is knowing that if I need to render a complex scene, Pflow or anything else, I can rely on Vray's speed and quality. Coming from 3ds Max/Vray and working in the motion graphics business, renders time play a very important role for me. I'm just starting looking at Houdini in my spare time. What difference exactly did you mean by 10% - difference houdini to cinema 4d or your to my render time in houdini ? Again, thanks for helping out. I guess I will try some dynamics to compare again. Is there a technique/setting to somehow make Houdini kick in to speed up the render? Not that I would want to render cubes all the time -), but sometimes you just have simple Geo. If I am getting you right, you are saying that mantra will perform comparatively better in more complex scenes (=more demanding of calculations), because Houdini does not help mantra in simple scenes. MickeyH Thanks for taking the time to answer, Marty, really appreciate it. Not all material parameters are supported, however, but for a fast motion test it is kind of like making a draft quality render in Cinema. It is an entirely separate renderer that uses OpenGL acceleration to draw frames. Don't be afraid of dropping down an OpenGL rop for a motion test either. This will report how long it actually takes to render the scene and other useful bottle neck times that might be occurring. Also, under Statistics try increasing Verbose Level above zero. I usually set them to 5,5,5 (reflect, refract, diffuse) for PBR style rendering. You can also drop Reflect and Refract limits to zero to basically run Mantra in direct lighting mode. Set Min ray samples higher than 1 for better quality. I usually turn off Ray variance, it has been known to cause flickering on animation sequences. The Shading Quality Multiplier can be leveraged if you have complex materials on objects and simply want to do a draft quality motion test. This speeds up the render a bit on my hexcore system. I change Tile Size from the default of 16 to 48. Inside the Mantra node in the out network activate the Rendering tab then activate the Render tab, below. There are a few basic things I do to speed up render on simple scene. Here are my specs, and just to be sure, I posted the file below: Mac Book Pro 2012 Retina Display i7 quad core, 2,3 ghz 256 GB SSD Nvidia GeForce GT 650M OS X 10.10.3 If someone could give me a hint or at least tell me whether this performance is normal, I'd be very thankful. The render times don't vary much, whether I render to disk or not. ![]() Also, MPlay takes at least up to two minutes to start. Seeing other peoples obviously using houdini on (probably) similar machines makes me think that I am missing sth. Not comparing apples to apples here, but cinema 4d takes less than 4 seconds to get something similar rendered. Resolution is set to 640X360 Rendering 10 frames of this scenes as a tif-sequence takes up to 4 minutes right now (pixel samples 1/1, min-max ray samples 1-4). For testing the render speed, I am trying to render a very basic scene: Just a default cube and a sphere moving around a bit, with a default point light and a camera. Hi there, I am doing a couple of little tests in Houdini apprentice to see whether Houdini should be my future 3d application. ![]()
