thanks guys, these new xml presets are just awesome. i particularly like the noisy setting. the calculation is exact. there is really a big improvement from 1.4 to 1.5.

updating this with another finished painting before. i treated the surface with mixed media paste to create texture before painting it.

Yeah, perfect. Well, it's time for me to go into post processing, too. These plants!

my apology for not mentioning. i used vray for sketchup and use Photomatch in Sketchup in setting up the background image and the foreground model. then after rendering i reinserted the image one more time in Photoshop. the advantage of photomatch in SU is to set up your camera model to match with the image, so that when post processing it's easy to match them together.

tnaks bartels for your comment. i think i should share her the amount of knowledge i think i gained in this interior test. This test was done using my old interior project to look on emmissive material. (kinda comparing LEM of Podium with Emmisive material of vray). I love the Light Emmitting materials of Podium. so when i use Vray i did not use any omni, sun or rectangular light. on this test i was glad that about the effect of emmissive material. but you can only increase the effect of it by decreasing the fstop value of the vray camera.
but one thing happen, a lot of dark blotches on the image in which i was disappointed. but i did not gave up, instead i increase the HSPH subdivision and the sampling number. i have done that after some of my previpou reading on the critical settings of vray. the IR (Irracsiance) has random calculation and if you want IR to calcualte more you have to increase the no. of subdivion and also the number of random samples... the third image was the result after increasing the HSPH subdivision from default 50 - 80 and sampoles from 20-30.. although the black splotches seems improve but traces of it still can be found... so i increase further the subdivion to 120 and samples 50, at the same time i have to decrease the number of IR passes to (-3,-1). the result was the 2nd image ( rendering time was mangeable over 44minutes.

second and third image, IR map has been saved and reloaded.. render time decrease to 23 minutes.
lightcatch and IR were saved and reloaded.. render time calculation for the last image was just 11 minutes...

i hope the above will be source of kowledge to everyone.
