[Max] I need help! / Tips for enviroment backdrops

« on: 2017-03-23, 01:52:52 »

I need some pointers on rendering a background that will be visible through the windows.. i feel like this is pretty basic and i just missed the memo. Normally i just add the background in photoshop but i would like to keep the look of actual glass window panes and the interior reflections that would be casted on them like the attatched picture.
Also how do i deal with the light thats casted from the background image? I tried a high res backdrop and since it wasnt a hdr image the light it casted looked kind of fake and ruined my scene, not only that but it somehow looked blurry even though i turned bitmap blurring to zero. Any help much appreciated thanks!!

[Max] I need help! / Any ideas on how to create a diffuse human skin map?

« on: 2017-02-26, 04:28:57 »

Ive been searching online everywhere and havent found much maybe someone here can give me some info,  how would i go about creating a skin map for a human model. It needs to be realistic and im obviously going to have to make a map for every part of the body (hands, elbows, neck,etc) should i just use high quality skin images or paint them or what.. it seems like a daunting task and im not quite sure how to go about it.

« on: 2017-02-20, 06:10:26 »

Not even sure if i asked that correctly but I just watched this video https://www.youtube.com/watch?v=m9AT7H4GGrA and im wondering if this also applies to corona?

So what color space is corona in by standard and how exactly do i go about working in other color spaces.. How many other color spaces exist? whats the best to use? any info helps thanks!

[Max] I need help! / How to get the "thin film" look in corona?

« on: 2017-01-30, 04:25:26 »

http://blog.maxwellrender.com/tips/pushing-the-limits-of-realism-of-materials/
this blog post from maxwell is talking about creating a glossy coating on a material that will give a "thin film interference" look.
I think this is kind of related to "dispersion" which i know corona cannot do but is there any other way to fake this or get a similar look?

[Max] I need help! / how to use a picture for a background enviroment?

« on: 2016-08-13, 04:29:18 »

This is probably really basic but ive never seen how to do this where you use a really high quality picture for the background and it looks real in the scene.. such as this picture ive attached with the red roofed building in the background.

Do you just put an image on a plane and render it, or add it in photoshop? I put an image of mountains on a plane and had it outside of a house window but it looked like total trash, very grainy and blurry and out of scale.. i wasnt sure how far away from the window to place the plane/ so yea im confused lol

[Max] General Discussion / is ambient occlusion neccessary in every render?

« on: 2016-05-13, 09:02:23 »

I thought it was more of a way to fake global illumination back in the day, but now that we are able to easily create global illumination do you still need to use it?

[Max] I need help! / This Image!!

« on: 2016-03-20, 04:51:45 »

This image is what got me interested in using the Corona render engine, I cant believe this image is CG.. This is from the gallery on the corona website its by  Eduard Caliman and I really wish he was on this forum so he could talk about it if he was willing too maybe give some insight into how he did it. I know its a combo of modeling, materials, lighting and whatnot but i just find it hard to understand how you can reach this look? I mean im a newbie and i spend hours tweaking everything and i cant even get a real looking image.
Where can i learn how to make my renders look like this and what is most important for this look materials, models, lighting, or what?

[Max] I need help! / how long should i be rendering for to get rid of noise?

« on: 2016-03-19, 05:48:50 »

I rendered this image for 2 hours and its still visibly noisy.. I know some of you render for 8 hours or more but is that necessary to completely rid the noise? This image was rendered with stock corona settings except for MSI set to 30.. so not exactly sure why it looks so bad.

Work in Progress/Tests / What more can you do to create realistic skin aside from SSS?

« on: 2016-03-07, 04:49:51 »

Im just playing around trying to get a realistic looking skin shader, ignore the symmetry seam lol.  So far this is what ive got.
Planning on making a high resolution bump/displacement map in mudbox that will have pores in the right places, some forehead wrinkles, and other bumps. Also im not sure if ive overdone the absorption? the nostrils look a bit too SSS.
Also i heard about using shadow maps, parametrization maps and playing around with the anti-aliasing can increase realism of skin but unsure how that would play out in corona
