volumetric images dropping FPS
Hey,

i was wondering if there's any trick for this,

i am using volumetric style images for my cloud ( and i love it )

but if the image size goes over a certain size, fps drop heavily. like a shittons =o

any way to go around this ? i don't want to be stuck with mini sized cloud pfft

i dont want to pack small cloud to do a big one, simply because i want the size of my cloud to change...

(because i gotta have to delete the exterior one 1 by 1 or when i resize them, move them 1 by 1... its not gonna work out well and smoothly...)

it is said in the tuto "volumetric images may not intersect with each other"... but why ? any specific reason ? what if we do ? drop fps ?

let me know !

For the intersecting: As far as I've seen, when they intersect, you get artifacts.

You don't have to increase the image size to increase the cloud size. The image size increases the quality of the texture without affecting the cloud size (this also gets a lot heavier on performance).
To increase the cloud size, do:

cloud.obox.box.set(average_size * rand_value);

Increase the average size (and make sure to spread the clouds out more), and you can set a random value to have more cloud size variety. But again, make sure they don't overlap.

In all honesty, a cloud library would be amazing. smile

thanks for answering tottel =)

mhhhh,

with this way, having cloud over a certain size even by themself create artifact ( big square that doesnt show any image in the cloud ) is there a way to fix it ?

like over 300xyz and they go boom : /

hey guys i gonna up this post because i still have some issues,

i managed to get it all working, but i have an issue with some artifact in the cloud now, when going over a certain size, lets say 300px for the sake, it works fine but not on the same Y as the cloud ( create an see thru artifact ) and its kinda annoying : (

i render the vol. cloud in RM CLOUD.

as for the shadow, i heard its only working for dx9, is it still this way ?

i didnt manage to get the shadow to work either, but i havent looked to much into it atm

thanks for your time

the project where it happens is pretty big

i can provide the script concerned tho if you want

image of the artifact
http://postimg.org/image/l2cljn1jn/

only happens on the same height as the cloud ( under or over works without issues )
