Evermotion video tutorial mini series (Grass and Tree planting with PFlow and VRay)

Hey Anselm - thanks for the reply. I am still waiting for Santi to reply as well, but I'm not holding out much hope. He's a bit hit or miss on the forum

I found that I can get the mo-blur to work with the standard camera and multi-pass blur, but that type of blur just doesn't seem to work with Vray at all. Are you able to get that working? It would be a shame if I can't: I think I need Vray to get the refractive effects I'm used to.

Multi-pass motion blur should work fine with V-Ray - you have to use a Standard camera though. For a V-Ray camera, you will have to go through Video Post.

Best regards,
Vlado

Thanks Vlado. I had tried it many times over with this file and given up on it - but after reading this tried it again. I found it worked but only with the Max Frame buffer (I always use VFB). Is that expected?

*edit* It's also crazy slow compared to Vray's mo-blur!

[PsychoSilence]

yeah, it renders the image for every step so with a substepping of 12 it renders the image 12 times for 1 frame pretty much...

on the tea pot/ water droplets scene i got a little angry because i remember some of the older particle systems in max and what they could do that i couldnt find in pflow. i was able to take a beer bottle (no, not rum for the ones that know me) and use a cylindrical gravity from maxplugins.de which drew the particles into the bottle but using a deflector they would stick to the bottle and run down (took three gravities for each part of the bottle to make it work but it did work) with the eratic movement of the particles i thought two different ways. the first was to set up the particles with an attractor which is also found on maxplugins.de or to hide a fixed set of particles that would repel particles. what i wanted is that pcloud has the option that if two particles collide there is a spawn with a death of the original particles, which i couldnt find in pflow. with this i could get a particle that would move on the surface of the bottle in a weird motion then join into 1 particle on collision. using spawning to leave a trail behind the originals then add the metaballs it would give a nice effects. but i think my brain out-thought pflow. maybe thinking particles could do it. hope it makes sense what i said because i is the weekend and we do love our rum in barbados

[PsychoSilence]

Hah! no worries, makes perfect sense The point of my tutorial was not to use ANY plugins tho. Gotta try your technique some day.

cheers to rum!

Sorry to dig up an old thread here guys, but.

I cant seem to get the trees to follow the greyscale image. If I check 'If location is Invalid, Delete Particles' all the trees vanish!?

The map is downloaded from the tutorial (once I found my own quick map would work) and is applied to the ground plane



I'm probably missing something so simple here, but can I hellers find what it is! Any help greatly recieved

Using Max 2009

Dear PDG, no sorries at all
Do you mind attaching a (maybe simplified) version of your scene? I will have a look asap and see what is going on. "If Location is Invalid - Delete Particles" should not get rid of all your particles

kind regards,
Anselm

Thank you for the reply Anselm

I have since tried from scratch again (well a couple of times) and now have the greyscale map working as it should. Using a standard material for the greyscale map, as opposed to a Vray material did the trick for me.

It looks great though so thanks for the tutorial. I'm sure it will come in very handy

One further question: After running the script to swap the particles for the Vray mesh the particle system can't be adjusted, can it? Would be handy if it was adjustable post script

[PsychoSilence]

That is true, after you swapped out the particles for instances thats fixed. in order to change the particle system you would have to change the system, delete all scattered instances and run the script again
