dogragurjeet Posted July 3, 2009 Share Posted July 3, 2009 Mock up of a swimming pool. Vray sun and sky, with vray phy camera. Tried to put up a background sky but turns out really different than the original map. Uring Irr. map and LC with reinhard color mapping (all values at 1 just gamma at 2.2 and affect background unchecked). Advice needed and urgently. Any help would be really appreciated. Made this in half a day, have to submit by end of week. P.S. Cant get a good material onto the water and the trees are just standby low res, will detail them out if i have time or will then turn to PS. There is no post work. Have used a HDRI image override for reflection but does not show up on the glass at all - it turns greyish black.???? Link to comment Share on other sites More sharing options...
dogragurjeet Posted July 4, 2009 Author Share Posted July 4, 2009 i know the rendering is quite below standard, but please some remarks to get me started, am stuck bad... thank you Link to comment Share on other sites More sharing options...
johnvid Posted July 4, 2009 Share Posted July 4, 2009 where to start is the problem, but as the water is your prefared problem, I think your fog setting might be too high, try .03 or .003,colour the water with the fog only not diffuse, the surface of the water is personal preference, but my opinion you need an alternate displacement on the water surface, combinations of displacement are even better, so you can have larger waves, smaller ripples multiple points, some regular noise, and some fractal noise for micro displacement, all at different sizes, make sure the water mesh has enough resolution for the waves, vray displacement will add its own resolution. get rid of the electric blue sky, and make sure you try the inbuilt sky, maybe warm the light up the nearer the horizon the warmer things look, trees ... get some better ones, or use 2D Maps/photographs or composite in some in. What rendering method are you using? Link to comment Share on other sites More sharing options...

What rendering method are you using? thanks for writing in .... really appreciate that. I could not get combinations of displacement?.... can u please show me with an example material? it would be very nice. I have been trying really hard to get it right but the more i try the worse it gets . will bring on the natural sky and then try it again. Thanks for the help, appreciate it a lot.

EarthMover Posted July 5, 2009 Share Posted July 5, 2009 I do quite a bit of pool renderings and something that I've recently started doing that seems to help a lot, is to not use a fog on the water refraction, but use a clear water and instead, paint the walls and bottom of the pool blue....as it is in reality. Also add some turbulence noise in the bump slot. For the water below I used the following settings in Vray - Reflection color - 178 with a falloff in the reflection slot and subdivisions at 20 Refraction color - pure white with an IOR of 1.2 and a subdivision of 20. Fog color is pure white with a fog multiplier of 1.026 Bump is set to Turbulence at a size of 150, High 1, Low 0 Levels - 3, Phase 0. The bottom of the pool is painted with a blue whose RGB is 55,157,229 and the hilight glossiness at .65 and the Refl. glossiness and .85. I'm sure there are probably better settings than that and some of those may not be necessary, as I'm still learning, but this is where my trial and error has gotten me. Hope it's of some help to you. -Adam Link to comment Share on other sites More sharing options...
dogragurjeet Posted July 6, 2009 Author Share Posted July 6, 2009 thank you so much adam... yeah will be putting up some newer renders... thought have submitted to the client, but want to improve upon the image. Adam will try your suggestion and material settings.... thank you again Link to comment Share on other sites More sharing options...
dogragurjeet Posted July 6, 2009 Author Share Posted July 6, 2009 i just wanted to know one thing. Do you use a plane for the water. I am using the entire mass of water, i.e. am filling up the pool with one big solid and trying to apply material to it... is that correct? Please advice.

dogragurjeet Posted July 6, 2009 Author Share Posted July 6, 2009 this is my try after applying your material settings adam. I loved the water effect in your rendering but seems that i am getting something very basic wrong. I just end up getting lots of reflection onto the water. If i reduce reflection then the area beneath the water turns absolutely dark instead of showing the color of the tiles below. Am stumped. If I upload 3d file with the settings can you help me please?

nodar1978 Posted July 6, 2009 Share Posted July 6, 2009 water, trees, view (composition) and maybe you can add some more stuff for pool, some chairs, ambrella ... to give more reality I'm not professional but this is what i think Link to comment Share on other sites More sharing options...
EarthMover Posted July 6, 2009 Share Posted July 6, 2009 i just wanted to know one thing. Do you use a plane for the water. I am using the entire mass of water, i.e. am filling up the pool with one big solid and trying to apply material to it... is that correct? Please advice. In my example, I am just using a single plane for the water. This could be the problem. What are you applying the pool tile material to? If you are just creating a box and applying the water to the outer/upper surface of the box, and applying the tiles to the lower/inner surfaces of the box, you would need to flip the normals on the inner polys, or they will show up black. I will usually create the shape of the pool with splines, then extrude it downward. Then I will select the polygon that represents the bottom of the pool, and move a detached copy of that upward for the water surface. If you post the .3ds, I'll take a look. I'm no expert, but I do a lot of pool rendering for my company. Link to comment Share on other sites More sharing options...
