      Sure thing, it's bit heavy as it has a large texture and a SDS form.

      I included the displacement map incase Vray does not automatically map to it.

        Thanks. I haven't tried to displace grass yet. But I liked your sample.
        Was curious to how the displacement looked like. That's a PS noise generating filter, right?

          That's a map I got online with the grass when I was looking for a displacement example in order to learn.
          I have been playing around using PSP making my own noise maps and concluded that the finer the noise the thinner the blades and visa verse.
          I also tried squares and dots and they create some really cool effects, especially using a variety of grey shades one can get varying hieghts.

            Using the above displacement map I mapped another texture onto a low poly sphere and it turned out pretty good, I did use 'soft focus' in PSP, I believe it's called 'Bloom' in PS.

              Last one for the displacement tests, using a single face (no thickness) with a texture and displacement.

              I believe displacement is under the belt, now the next thing I need to get a grip of is D.O.F, anyone got any good tips that can help?

                The rug and fur displacement looks the best. I've yet to see a grass displacement that works up close, But it does work for smaller patches seen further away.

                DOF:
                You must use Physical Camera.
                The "Override Focal Dist." only takes inches as it's unit values. Nomatter what the model settings are.
                Once you've set the focal distance, adjust the F-Stop until you get what you want in focus in focus, and adjust Shutter Speed or ISO to compensate for changes in light

                Tip: while you dial in your DOF, render small and use "Override Materials" under the General Switches flyout to cut down render times.

                    just wanted to correct thomthom there, physical camera is not necessary for DOF, it works with both cameras

                                    I did some quick tests.

                                    I found that I had to put all the faces that makes up the glass into one group/component. If each glass was an component instance they'd get the same distortion. Didn't find any way around it other than exploding all the glass faces.

                                    Below is a test render.
                                    The Bump map is the default Noise map where I set the Size to 50.

                                      Cool glass distortion thomthom, I used the same technique for making high gloss malamine panels.

                                        A slight variation:
                                        Bumpmap: Blend
                                        - Texture A: Noise - Size: 50
                                        - Texture B: Bulge
                                        Blend Ratio: 0.25 (75% Texture A)

                                        This just add the slight bulging which you often see in windows.

                                        Yea. I have Pro at work. But not at home. While I've been testing Windows7 I've installed the Pro version, giving me 8 hours of Pro playtime. But that's a while since it ran out now. 😞 I should get the Pro. But I also want to buy the Arroway collection package. I did buy V-Ray for my home computer last month 😄 . (New Your trip didn't happen 😞 ) But this month I bought myself a new bow which I'll pick up when I go to London next week. 😄 But that means not more fun stuff this month.

                                          2 questions:
                                          1 - if I explode all components, wont the model size skyrocket?
                                          2 - Matthieu Noblet script to reduce VRAY Render Times (parsing time) seems to already do that... as far as I understand (true, I didnt understand very well what it means "assigning textures directly to geometry)... anyway, if I use his scrip, will it automatically do what you said? If it does, I wonder how I would be able to MAINTAIN one noise texture to all glass panes (if that was what I wanted)

                                            Depends on how large the mesh inside component is. But generally I find geometry to add very little to the file size. It's the textures that blows the file size sky high.

                                            No. His script is to transfer all material applied to the outside of components and groups to the actual geometry inside. VfSU chokes when you apply materials to the outside of components/groups.

                                            The thing is, if all your glass are instances of the same definition, then they will all look alike. It seems that the Noise texture is generates identical from the 0,0,0 point of the component that contains it. This is probably to be able to render animations without having the noise whirl about. That's why, that if you take all your glass components and group them, so all the glass components are now inside a single group, and you then explode all of the glass; the noise will then generate it pattern from the 0,0,0 point of the group and generate a different pattern across all your glass surfaces.

                                            Practically I don't think you have to take all the glass into one component. But enough to break up the repeating pattern.

                                            Disclaimer: I don't know the behaviour of the noise as a fact. It's just what it appears to from my observation. I wouldn't be surprised if Damien saw this thread he's say "no no no, that's not how it works at all.". 😉
