RGB plastic pegs
RGB plastic pegs


RGB plastic pegs
Description: Modeled in wings 3D. A combination of standard bryce sunlight, point light sources and Horo's "corridor_night.hdr" being rendered as a background (but not actually being used to cast any light on the scene). The most difficult aspect of this image to get right was the plastic material of the pegs, many attempts resulted in the pegs casting "shadows" which were somehow brighter than the ground around them (some issue I suspect with the render engines handling of transparency where multiple light sources are employed - the same issue arose using the hdr to light the scene).

Simple yet wonderful. RGB - basic colours. I'm always awed at your proficiency to create such simple yet elaborate models in wings. Excellently lit. Interesting use of an HDRI as background without using it for light. Narrow FOV -- never thought of that. Next time, use wooden pegs if that's simpler to render ;-) Beauty in simplicity, 5/5.

Horo describes it perfectly. 5/5

Thank you.

I don't know that I would consider wooden pegs simpler... I've never been entirely happy with the wooden materials either supplied with bryce or those I've made for myself. Plastic, metal, glass - these lend themselves better to simulation than organic materials which seem to fair better when applied in the form of bitmaps - Rashads leaf for example. The plastic peg if anyone expresses a desire for it I will happily upload as a model in the exchange. I cheated with the spring and cut it in wings so it could be articulated to accomodate open and closed pegs - also in the image you might have noticed that the spring in the centre is wound tigher than the ones on the peg to enhance the impression that they are actually capable of "springing". The most critical thing for this image was the way bryce handles the plastic material, look carefully at the shadow of the red peg around where the spring is and then compair that with what is visible of the spring through the body of the red peg. The shadow does not look right to me, the refractive properties of the peg combined with the large number of lights around the scene should have almost eliminated such a strong shadow - that is partly the reason a slightly reflective ground plane was used to disguise this issue somewhat. The other reason was to reflect the hdr background and so add to the level of realism - the hdr background also helped with the springs, which although small, really benifit from reflecting the hdr background as opposed to a generic bryce sky. Our visual sensitivity to such details seems remarkably high, this was discovered when I shifted from lighting the scene with hdr to lighting with point sources. My first move was to ditch the hdr altogether, which really degraded the realism of the image - even though I was employing more lights than the IBL had simulated - so that's how I deduced that I needed the hdr as a background - even if there is not much of it to see, it does the trick.

As usual - precise modeling work in Wings and effectively lit and textured in Bryce. The hdr really helps the trick. You just have to know what you're doing. Here the result is obviuos. A really nice render. The minor thing I consider not to be so convincing here is with the green "broken" peg. The half which rests its end on the red peg shows too clearly the second green half-peg due to a strong transparency. Perhaps this has to be edited separately from the other parts in scene, but since it will make the object to look noticeably different from the other, I just don't know if it'll be a good idea. Nevertheless - a 5 from me.

That little detail about the spring in the red peg and its reflection you pointed out is an interesting one. We cannot notice this for the blue peg, which looks right. It looks as if the surface the pegs are on works as a filter - I don't think you used an x-ray light source. It may also be the transparent property on the peg acting differently on different light angles. Amazing discovery, probably hard to exploit.
