''Veins''

[mitzzy50]

Hello everyone,
I recently bought a product which gives the Michael 4 product something that looks like ''veins'', in the head and chest, as pumping iron. From what I see in the materials tab in Poser, it place 2 things. A diffuse map and a displacement map (I hope I'm not confusing things here...). And when is rendered in Firefly of Poser, it looks kind of cool. But when I render the same scene in the plug-in for Poser, I can see the skin as if I didn't apply the veins product I bought. Any idea why is that? Thank you in advance

Without seeing the Poser Material, it's hard to know what the product is doing.

If you want to overlay the veins on the M3 map, there are a few ways ...1) Photoshop, 2) material mix, 3) material multiply, 4) put the none-vein area of the vein map as alpha and use a material mix with the mix amount being the alphaimage, texture1 being the M4 map and texture2 being the view image map.

Without a doubt, the highest quality output would come from option 1) above (and I'm sure most Octane users would recommend that), but it you are into learning Octane node tricks, try 3) since there are some neat tricks you can do with alpha.

For the displacement map, it depends on the quality. If it's a genuine, actual displacement map, you could out it on the model in ZBrush and convert to a normal map and use that in Octane. Otherwise, just use the displacement map in the bump slot (you might need to invert it).

Thank you for your quick help. Hmmm I hope this is helpful...

Picture name 2.jpg: Skin with the ''veins showing up''... Idk how to say it well...

Can you see what the product is doing? Maybe you know what is causing that I can't see the effects of it in the render by the plug-in

Would it be possible to see what Dfs_V4Torso_Map and Dsp_V4Torso_Map look like pls? Just flip open the preview of those nodes - that will give us a better idea.

I guess you will have to zoom in a lot to see the veins maps

Mmmm, I'll be honest....mixing one texturemap with another via nodes is not going to get you the best outcome. Whilst you could convert the backgrounds on the images to alpha and get an OK result, it's probably not something I could walk you through in a reasonable amount of time (and the outcome would still not be that great). Much much much better to purchase an M4 texturemap with veins on the actual skin textures. Or you can photoshop the ones you have purchased onto the standard M4 textures. The results will be way better.

Well... It looks pretty nice with the firefly renderer... Special in the M4, in his arms, looks like he's really lifting weights, because the kind of pump out of the skin a little bit. I guess that's the displacement right? I think I won't get that effect in photoshop, right?

[face_off]

Yes, that is probably the displacement. Hopefully one day soon Octane will be able to do displacement. In the meantime, if you are keen, you can use "normal" maps - which is what the attached image uses. You can use ZBrush to convert from displacement to normal maps (unfortunately there is not an easier way).

[mitzzy50]

Oh wow... But I have no knowledge in Zbrush... Neither the standalone version does displacement?
