You might want to watch this https://www.youtube.com/watch?v=HHsRRLCAOm8 and there are several plugins around for UV mapping http://sketchucation.com/pluginstore?pln=tt_uv_toolkit http://sketchucation.com/pluginstore?pln=UVtools http://sketchucation.com/forums/viewtopic.php?f=323%26amp;t=57270

@unknownuser said: Where is this screenshot, can you show your model and see how i can help, i use sketchup for developing games and it works effectively My bad, I thought it uploaded [image: lDZH_screenshotmeshlab.jpg]

Try RC3

@panixia said: thank you. that's pretty nice stuff.. in addition i discovered that i'm just logged to it as if i used it in the past, but can't remember when or why i did it! This happens to me so often, it doesn't bother me anymore

My apologies, but that doesn't look very realistic to me at all. You shouldn't have the need to repeat an HDRI tiling. They are created to be used as a spherical environment set 1 to 1. The best way to achieve the most realistic results would be to have a photo taken at the same time of day and location as your render and place it in your background in post. Here is a great site for getting background photos as well as textures. http://www.cgtextures.com/

I have similar problem. no caustic effect at all. Vray 2.0 for sketchup 2016, dongle in 1.49 I had no problems with caustic. my settings: scene units - cm pool size 400x400cm depth 0-100cm (4 steps) pool - solid, grouped, default material water surface - single plane, separated (grouped), material "pool" applied on both sides. material "pool" (default settings skipped): reflection layer: fresnel b/w 1.33/1.55 diffuse layer: texture - irrelevant jpg, transparency 100%, IR -1.33 refraction layer: IOR 0 1.33, FOG light blue, multiplier 0.005, dispersion - off/on (it changes nothing), Abbe - 50, affect shadows - ON/OFF (it changes nothing) options: double-sided -on, cast shadows - on, trace refl. - on, trace refract - on, reflect on backside - on, max refract. depth - 5 displacement: x2, texnoise size 9, vray options based on default settings (by load defaults button) global settings: reflection/refraction - on environment settings: GI skylight - caustic subdiv - 1000, caustic multiplier - 1-10 (it changes nothing) Indirect illumination (GI) settings: GI caustic reflective - on, refractive - on caustic settings: caustic - on, max photons - 5-30 (it changes nothing), max. density - 0, multiplier -10, search distance - 5-20 (it changes nothing). camera settings: default, physical output: 800x600 any ideas? thx for help
