Ricardo Eloy Posted January 24, 2008 Share Posted January 24, 2008 You can use SuperSpray or even PFlow for a basic rain effect. More complex stuff, RealFlow is the one. Link to comment Share on other sites More sharing options...
robkar97 Posted January 25, 2008 Share Posted January 25, 2008 I think there are a few rain sample scenes with the tutorials that ships with 3ds Max. Check under Particles. Some use the PF Source and different particle systems for the falling drops and the splashes from the surface of objects. Looked very nice, and was pretty simple to customize.

pipjor Posted January 25, 2008 Share Posted January 25, 2008 i do this in post( After Effects), gives you much more controll over speed, angle etc... Link to comment Share on other sites More sharing options...
Eric Sosa Posted January 25, 2008 Author Share Posted January 25, 2008 @ allu..thx for the tutorial, I'll have a look at it. don't have "after effects".. Real Flow...is that a plugin? have tried the superspray but the particle shape looks very primitive. hope to find a better solution with the other metods suggested...thx anyway Link to comment Share on other sites More sharing options...
robkar97 Posted January 25, 2008 Share Posted January 25, 2008 I would use the PFlow source and set the particle type to Shape Facing with a W/H ratio that made them long and thin, then add an appropriate opacity map like gradient ramp from white to black. Some motion pmotion blur would add to the realism. Good luck! Robert Link to comment Share on other sites More sharing options...

Ricardo Eloy Posted January 25, 2008 Share Posted January 25, 2008 LOL.... Robert - take a look at the Help files. You got already what you need for rain, it's just a matter of setting the particles right. Link to comment Share on other sites More sharing options...
Eric Sosa Posted January 29, 2008 Author Share Posted January 29, 2008 hey guys...sorry for the late update. I finally start to understand the rain thing, using the particle flow, Robert & Rick mentioned..good tip guys, thx [ATTACH]24415[/ATTACH] the only problem now is...the pmotion blur is only supported with spray, super spray and clouds but not supported with PF I can assign the pmotion blur in the mat opasity map slot but it does not give any "blur" effect..ughh. any other idea of how to make the particle blured enougth to make it look like real rain? sorry for all this begginner questions....

FlyinHawaiian Posted February 3, 2008 Share Posted February 3, 2008 Motion blur it! Setting motion blur for a PF Source is slightly different from the way you enable motion blur in regular objects. You need to bring up the Particle View, select the box containing your PF Source and bring up properties (right click). It is only there that you can enable the PF Source's motion blur parameters. The motion blur properties for a PF Source object that are accessed through the right-click menu in your scene does not effect the motion blur properties of the particles. This is so that you can have specific control over motion blur in separate Pflow events. (accessed through right-clicking on the event box and going to properties in the box that comes up.)

Eric Sosa Posted February 4, 2008 Author Share Posted February 4, 2008 THX JOEL!!! ....I knew u wouldn'y let me down! . u'r my guardian engel , i ougth u a drink I'll try and post a result as soon as I can....that "rain" project is only in my weekends spare time. cheers mate....Eric btw....I'm still trying to figure out about the script for the vraydisplacment grass ....

FlyinHawaiian Posted March 3, 2008 Share Posted March 3, 2008 Well, it depends on what renderer you're using. If it's Vray or mental ray, you don't even have to enable motion blur in the PFSource properties. Just enable motion blur in the render dialog box (Vray motion blur render settings are under "Camera". Mental ray motion blur render settings are under "Camera Effects" ). If it's scanline, you need to both enable the object or image based motion blur in the PFSource and also enable the corresponding motion blur under the the "Renderer" tab in the render dialog box. Unfortunately, unless you tweak your rain material a lot and the motion blur settings, your rain will still probably not look that much better than the sticks you currently have going on (With the exception of some blur on the ends of the particles). I would highly recommend using a post editor to tweak your results on the tail end. (Photoshop if you're generating a still, and something along the lines of after effects or combustion if you doing an animation. If you don't have access to these, see if you can take a frame sequence to work and use their software, or maybe a friend might have it. Either way, if you want truly realistic work, these tools are a must.) I've worked on countless waterfalls, and fountains, and post is really where the work begins to look good. Good luck!

FlyinHawaiian Posted March 5, 2008 Share Posted March 5, 2008 this is real rain. the one with duration 0.002 is better out of the rest...I think. - I agree. doing it with photoshop...how can I chose only the rain and blur the ends?, making two renders from max = 1 x rain 1 x scene and mix them in ps? - You got it. rain/drops) colour, I did apply a transparent vray mat to the PF but it does not have any effect on the rain... - Need to add "material static" to your pf source in the Particle View. Copy the material you want to use in it's material slot. -Pflow is not like static geometry where you can just apply stuff to the PF Source. You have to get into the Particle View and experiment with all of the actions and tests, etc, to get a feel for what you can do. thx for all your help Joel...realy apreciated You're definitely on the right track! The secret to it all is reference, reference, reference. The only way to get good at emulating real life is to refer back to it. Keep it up! Rain is starting to look better. (Also, notice the light blueish color of the rain in your reference. You can easily add or adjust this in PS. I honestly wouldn't bother too much with trying to dial it in in Max, get it close, then, tweak in post!) Link to comment Share on other sites More sharing options...
Horhe Posted March 5, 2008 Share Posted March 5, 2008 Well in the old days Indians use to make a rain dance in order for it to rain... but i really dont think it would succeed here... What you need to do is to produce a photoshop brush that is similar to those on the photos youve posted. That and some randomness and variations and youve got yourself some believable rain without all the pain of a looooong render. Link to comment Share on other sites More sharing options...
Eric Sosa Posted March 6, 2008 Author Share Posted March 6, 2008 but i really dont think it would succeed here... totally disagree mate, making rain, in this case, is part of a 3D learning proccess, it may be part of your everydays work and... you always get something good out of it.....I will Link to comment Share on other sites More sharing options...
