Flash / Animations

~Sexy Toga Walk~

Aaaargh, the challenge - this animation was complicated. First it would spike when looped, and then the speed was too fast and Poser doesn't support scaling animation curves. I had to shift keyframe interpolation to slow the animation down, at the cost of motion smoothness.

Since the walking motion and the boob bounce were separated into different animation layers, interpolation introduced a lot of motion noise that later required more manual keyframe cleaning.

And then cloth simulation doesn't produce a loopable animation, but that's the way it is - simulations are unpredictable. The body motion loops fine, but the cloth simulation does not.

In the end, because of the time it would take to render, I disabled shadows and instead used per-material raytraced ambient occlusion nodes. It was still rendering too slow (in a 4GHz quad-core machine), so I pumped the pixel sampling rate and irradiance caching way down to speed it up. I think it still looks acceptable, all things considered. So much for just 60 animation frames! LOL

Figure is V4. Animation, cloth simulation and editing done in Poser. Hope you like it and thanks for coming by!

i had the same problem with dynamic cloth and a walk cycle.

even with form fitting stuff.

with GI off and 2 rays for raytracing, 8 lights, 4 with raytraced shadows and a reflective floor, it takes me about 10 minutes on 10 cores to render 32 frames of 600x800 PNG images. (using pp 2010 network ffrender)

I have yet to try network rendering with PP2010 over here. The i7 with 8 logical cores + the Core2 Quad could potentially make a 12 cores rendering farm with just 2 computers on a GigaByte LAN, all native in 64-bits. I already ran some tests on the i7 to see if hyper-threading would really improve rendering times with logical cores, and it indeed beats 4 physical cores with a good margin. My previous attempts to network render with Vue were quite disappointing, though, and I can only hope Poser can do better.

the fastest multi-core network rendering i've seen has been in carrara. i have high hopes for 8-pro.

i noticed the same thing about vue, although it seemed to be how it was moving data between the machines. very, very slow. even on a Gb LAN.

carrara seems to speed up linearly with the number of cores you add into it.

no idea how hyperthreading helps, i have 8 physical cores on the dual quad core Xeon in the MP and 2 cores in the core2 duo MBP. i got rid of anything less powerful than that, replaced my 1TB server MB with an underclocked CPU (athlon-64) for ultra-low power, and I can't use the rest of the MBs around the house since with laptops they're typically in suspend or on batteries. the rendering engine goes through battery pretty quickly.

i expect there's a way to tunnel the data over a WAN, I wonder at what point the network queue starts to become bandwidth constrained. Looking at it, it keeps checking the assets needed for each frame, each time a frame is rendered. Probably because nodes can come up and drop at any time, and it's not swift at accounting for nodes.

i had always envisioned a kind of WAN based render farm. certainly, most of my cores are idle most of the time. would be great if other people could use them.

My first attempt with Queue Manager failed miserably because I can't get my two Win7 PCs to network correctly. There are layers of security involving both Win7 and the router box, which has its own firewall and IP filtering. Windows 7 has been the most problematic OS I have ever seen, where networking only seems to work intermittently at random. Either one PC refuses connections from the other and vice-versa, or I have complete PC isolation from the network like if it was not really there. At one point both PCs can communicate perfectly, and the next time one or the other is refusing connections. As if not enough, computers disappear from the network at random times for no apparent reason. O_o;;

Add to this that Poser Pro 2010's Queue Manager is requesting specific port accesses that need to be configured on the firewall for each computer, but neither sides can ever find the ports open no matter what I do (I also allowed the ports on the router box to no avail). Considering how random Win7 networking has been here, I am not surprised the whole thing doesn't work. Setting up a Win7 "homegroup" has also proven a nightmare, where it only worked the 1st time I tried, and then never more... >_<
