Indigo Renderer Forum

hi! i'm sorry but i haven't found a topic same as what i'm about to say.

i got this error message---> "Memory allocation failure."


does that mean i don't have enough ram? hehehe. but i did a scene before with much more meshes and materials and stuff but i didn't get such error. Whew.


thanks in advance. i'l ty to include the image tomorrow i'm very sleepy lol.

It would be helpful if you at least tell us what version of Indigo you're using.

exactly.

its not the number of meshes or materials that count, its the polygon count and resolution that use much RAM. try to render in a smaller resolution or to reduce some meshes polygon count.

also light layers take a lot of ram. each light layer adds a huge ammount of ram.
(heres a formula to approximate the ram needed for 1 light layer: width*height*32bit*3/8/1024/1024. that means a 1600x1200 layer needs ~22mb ram, please correct me if im wrong ^^)

that means a 1600x1200 layer needs ~22mb ram, please correct me if im wrong ^^)

Supersampling exponentiates that value. With SSx2 you'll need four times the original RAM, but SSx4 already requires 16 times more than the original (352 Mb for 1600x1200). For light layers you need to multiply that value on layers count.

right, i forgot the supersampling:

width*ssf*height*ssf*32bit*3/8/1024/1024

thanks for the reps!

i'm using indigo 1.1.18 blendigo 1.1.14. didn't increase the supersampling value.


here are the images.

How much RAM do you have?

4 GB of ram.

(width*height)*ssf*32bit*3/8/1024/1024
or
(width*height)*(ssf^2)*32bit*3/8/1024/1024

Gerbin: do you have a 64 bit OS? if so try indigo 64 bit.

OnoSendai: 32 bit here

i tried deleting one of the chairs in the scene and it rendered well. but then i have to add more chairs .

and more objects too.

Chairs in your scene are the same. I hope you made them as instances, not mesh copies?

Just so you know, with 4 gb and 32-bit OS you want get to use all your ram you will only be able to use 3.5 gb.

with 4 gb and 32-bit OS

Namely, Windows OS. In Linux there is no such problem. ;)

thanks for the replies (i feel special hahaha).


@SATtva: that's what i did yesterday and it worked hehehe. i forgot i did shift+d in blender instead of alt+d. wahehehe.


thanks a lot guys. il try to post it here when its done so i could hear your comments. arigato minna.
