Dummies

Oh wow...

I see. Perhaps you mean the effects of radiosity, or caustics, things bryce is not so good at. The light bouncing up off the floor is a radiosity response, the translucent glow, caustic. If ibl and transparency got along better in bryce David would likely have applied transparency. In fact the "glow" you refer to is the same in plant leaves which is why I created the leaf mats, because not all forms of transparency in bryce can cause a glow the way you are correctly describing. Perhaps the ambient channel is the answer, although not a very good one. It would lighten shadows, but in a flattening 2 dimensional way. The ambient channel is a poor substitute for real radiosity. I would go the route of no ambient in this case as David has done here. In a perfect world David could apply super weak lightsources as secondary or bounced light indicators to do that caustic and radiosity bouncing for him.

Well, In this lighting conditions (strong lights from different directions) the floor, which is matte will disperse reflected light in all directions, creating ambient light. It means the dummies will get the light also from bottom. And the plastic material of the dummies, has some translucency - when you put strong light on it it seem to "glow from inside". Briefly: this is an abient scene with translucent object. In real life this could be recreated by putting someting plastic (I used BIC lighter, stapler, and box) ;) on white sheet of paper, and go outside in cloudy day (but not very dark). Shadows are wery weak, and real, full shadows are present only around the places where object touches the ground.

I'm not sure what you mean popgriffon about the shadows being too deep. Can you explain? For me it looks just right, since the plastic is solid and not at all transparent. Also the lighting is not even all around, there is always some bias of intensity causing some areas to be more lit than others, casting shadows.

Plastic Rubber looks very realistic, yet the plastic material has too deep shadows for my taste. With this lighting - strong, but dispersed light, shadows would be almost invisible..

Thanks for the information. I had never attempted rendering ibl with premium effects because the render times for me would be enormous. Nice to know that one can render at a lower quality while engaging soft shadows and it turn out to be this good.

IBL quality 256. But bear in mind that since I was using Premium effects anyway, (to get the softened transmission and speculative response from the nipple material I wanted) I also switched on the softshadows - this has the effect of dithering the lightprobe making it possible to get away with lower settings. Normally I would choose higher IBL quality over premium effects because it is more efficient, however, where premium has to be used anyway, I decided to cut my lossess and engage the soft shadows. It does not affect any of the radial lights used - unless they are also set to soft shadows - which is slightly inconsistant of bryce... but there you go.

Curious, what was your ibl quality setting? I see little banding and since this is a flat white surface I'm guessing the quality must have been very high, at least 1024. Please let me know.

a little late with my comment am I not :) Doesn't matter! This dummy, along with your previous cake-bakery and spark plugs entries, is one of the most realistic close-shots you've done in my opinion. As stated above - a true 5er. I guess you have played awhile to get this awesome material right; it payed off, David. The only thing which can be done is perhaps to "loose" the neutral environment and place those dummies somewhere on your bathroom sink..Well, your choosing!

Fantastic! The rubber is excellent on your pacifier. The plastic ring and mouth piece have just enouth shine. Really great work! 5/5

The rubber part is absolutely convincing. Lighting is excellent. I reckon the specularity is from the reflection of the HDRI. Simple subject, superbly done.

Thanks! Er... baby... oh I think that will take some doing. I think I'll have a go at dirtying my bathroom sink some more first. Gat is of course right about the plop render, and I did employ that to some extent since I had to have serveral goes at the "nipples" before they looked just right. Here's the specs of my machine. 3.4 ghz Prescott Pentium 4 processor 2gb ram 2 x Server HD's set to Raid 0 Graphics card - is actually not very important, partly because it only really is put to the test by the horrible openGL modes, but mostly because it is broken and had developed some excentricities about what colours it will be preparied to display... :(

Lovely! Now, just render a convincing baby and we can start a day care center. David, you must be working on an incredible computer. In general your image output is very fast which is good because it keeps your creativity flowing, and your quality is very very good which means it takes time to render. Very impressive work once again!! Keep them coming!

. nice work dave, great model and great materials, I am glad you went an extra step and rendered using that specular trick. but you know you didn't have to render everything at 64rpp, you could have used the box render :D

jelouse i am jelouse that rubber loods great looks like it just came out of your mouth nice work david ( cry cry sniffle )
