Super Hero Suit for Genesis 2

Hi - I'm just wondering if anyone has used this suit in Reality and Lux.

If so, can someone let me in on the displacement settings I need to use for the suit to show up in Lux? If I send it as it is, then only the cuffs of the gloves are visible in the render.

I have contacted Smay, but since he does not use Reality/Lux for his renders, he commented that it may be the displacement settings that are not getting transferred.

I upped the settings in Studio but they do not convert across; upping the settings in Reality lead to what can only be descibed as a tangled ball of polygons!!

I could go through some trial and improvement but wondered if anyone has already done so?

Anyone?

    With reality, try using 3 levels of subdivision when using displacement to avoid the mess.

    Fast reply - thanks.

    I don't have the suit, but to expand a bit on Matty's response: Lux does displacement by pushing around the vertices of the mesh. If the displacement map has a lot of fine detail in it, it needs a lot of vertices to push around. Hence why you often need to increase the subdivision levels on items with displacement. The other option is to use microfacet displacement in Lux. This does not pre-compute the additional vertices and displacement like Loop does, so uses less memory (high levels of Loop subdivision can use considerable amounts of memory), but is orders of magnitude slower to render as it must calculate the displacement at every ray intersection. So if you have the memory, it is preferable to use Loop. Keep in mind that microfacet displacement uses a different scale for the subdivision levels. The exact formula is on the LuxRender website in the Wiki, but 500 microfacet levels is equivalent to approximately 9 levels of Loop subdivision.

    The other option is to do the subdivision in Studio itself. Reality (and I presume Luxus) will export the fully subdivided mesh from Studio to Lux. I usually do this with the humanoid figures (e.g., V4, Genesis, etc.) as Studio's subdivision gives better results on their mesh than Lux's Loop does. Lux's Loop tends to have visible striations in curved areas such as the shoulders, breasts, etc. Given that this suit's topology is more akin to the humanoid figures, you might get better results applying the subdivision in Studio than in Lux. (To apply displacement in Lux, you must always have a minimum of one level of subdivision specified in Lux, so keep this in mind when deciding how many levels to apply in Studio.)

    Thanks. I think I shall try it again but subdivide in Studio first.

    In another thread mentioned about push modifier that help space out the skin and the suit a bit.

    edit > geometry > Apply push modifier and mess with the modifier dial in parameters.

    This method helped me when I was using luxrender with this suit.

    Again, thanks. Just tried that with the genesis bikini that had a similar issue and it worked a treat.

    Thanks all.
