Hi there!

Yes, there is, and there has been for quite a while: you simply go to ChaosGroup Website, register (it's free) and you can download Vray for Sketchup for Mac Demo.

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

Not sure of his units settings but I use decimals (.) in all of my parameters with no problems. I have never seen anyone use commas (,)

The "Ruby Console" is 'built-in' to SketchUp, it's always available... so use:
Sketchup Menu > Window > **Ruby Console**...

BUT, before asking such simple questions, please try to learn to use some of the myriad of Help files and search options that Sketchup offers - it clearly explains this particular issue here, when used with a with an search for 'open Ruby Console'...

Normal maps work in 2.0

Taken from another forum... "Normal maps are just bump maps that allow for the appearance of a bump in any normal direction, not just at the normal. That's the problem with bump maps - everything appears to come "out" of the bump at exactly 90 degrees to the surface of the poly. That's why normal maps are full colour - the three colour channels correspond to the local XYZ space, as opposed to the single channel for bumps."

You are geniuses !!! THANKS !

I had tried that but i one sided it on v ray and that just make it craches so i drop the idea ! When it was right there from the beginning !!!
Too bad it won't work for 3 objects but... well i have wait so long for that solution i can spend some time creating flat images of my 3D stuffs with the right angle.

A really BIG THANKS !!

Hello !

I'm starting with V-Ray for SketchUp and i'm interested to find where i can buy proxy objects like trees, grass et flowers.

Can you help me with that ?

there are various causes for this to appen. try exit the application and restart.. then try to ovverride materials.. and also you should give more information about your model, materials etc..
anyway there are a lot of discussions about this..

lejzidejzi - 1.49.02 was never released, and is a pirated version. Please upgrade to the latest version of V-Ray, in order to get access to a 64bit version of our product. The 4gb patch that you guys are talking about, just turns on LARGEADDRESSAWARE, which is on by default in SketchUp 2014 or later. SketchUp 7,8, and 2013 did not have this turned on, and in that case, this patch could hack the SketchUp executable to access up to 4gb of memory (golf clap), but the 64bit version can access more memory than any workstation can possibly have for the next 5 years. Please do not attempt to hack the very outdated 1.49.02 with this patch, it's dangerous, and it shouldn't change anything at all if you're using a version of SketchUp that was made in the past 2 years.

hi chon,

i´t s great, at the end i´ve found it!

man, i´m glad that was a trivial problem 😍

thank you all you guys !

um, silly question, but are you trying to render a line in vray? If you are, you need to give it a face. Vray doesn't render lines, no matter what material you give it.

You could also share your test file and maybe the answer is in there.

lol no i wasn't trying to render a line thats why i was using toon material 😛

Unfortunately I can't....

hi solo,
thanks for your answer and kind offer to upload a model of the lamp.
that´d be very kind of you!

woooooooooooooow!

I finally did it.
Thank you so much for the help Master Thomthom!!

Thank you also for this great community...

Render 1

Render 2

Open the vray for sketchup option.
Under "Camera" Roll-out go through the 'CameraPhyical'
Then check the 'Zoom Factor' option.
It should be 1 if we dont V-ray to zoom the view.
1 is default value.

thank you fro replies.. i find the problem.. it was in the refraction layer the color was black when i turned it white it was fine then 😄
thank you

Hi, I only speak Spanish.
I have a similar problem with "BugSplat" and I have a response to a possible conflict.

I deactivated the box "USE HARDWARE ACCELERATION"
The "BugSplat" disappeared.

the problem may be in the Hardware or drivers.

If someone helped this track, just ask.
Bye, greetings to all

In Spanish/en Español

A mi me parece el "BugSplat" aun que sólo cuando se cierra el programa.
En un momento desactive la casilla "USAR ACELERADOR DE HARDWARE" y el "BugSplat" desapareció. asi que puede ser problema de compatibilidad del Hardware o de los drivers.
...

Si alguien le ayuda esta pista no dude en preguntar cualquier otra cosa.

Saludos a todos.

one quick troubleshooting advice: are you running more than one window of Sketchup? There are some bugs that occur if you have more than one instance of vray running at the same time. Try using only one window of SU and see if the problem goes away.

i find that it's a lot cleaner create a new material, load that texture and properly map it on the geometry rather than import an image and place it onto geometry from file/import etc.

create a regular material and always check if it's applyed on the front face.. maybe this will help vray to avoid this strange behaviour.. also, if you need to scale/place the texture in a more effective way than the native "texture position" tool, i suggest to give a look at thrupaint by fredo6, thomthom uv toolkit may be helpful too, as it provides a tool to fit texture to quad faces etc..

This happens to me occasionally when I have changed the colour/transparency of a vismat material and/or I have an imported model with an unrecognised texture.

In the first case, I tend to save what I am working on and exit, when I restart it all worls fine.

In the latter case, if you are using an imported model, it may be worth removing the textures from this model and re-applying them with either native or vismats.

Hope this helps
