Scale Material Larger

Hi,

Sorry if this has been posted somewhere else before. I'm using this awesome Cold Pressed Watercolor filter by Heliagon.
https://www.filterforge.com/filters/11073.html

My problem is that I'm making a large format sign panel that is 36"(h) x 60"(w), so the texture needs to be seen fr om the road. The filter doesn't allow me to adjust the pattern to a larger resolution. I roughly need the pattern to be about 600% larger than it is. The current size pattern won't be able to be seen from the road. One issue with oversizing the render and then cropping it down is that the size of the file will be massive. I was wanting to use the tiling feature to keep the size down. Is there a scaling node I can add somewh ere in the pipeline that will let me scale the pattern up before rendering? The sign shop my customer is using say they want the dpi setting to be 1000. If it was lower it would be much easier for me to render and then crop in Photoshop.

Thanks for any help and advice!

Thanks SpaceRay for the reply,

I wanted to used the seamless tiling so the image wouldn't be so large. For some reason the print shop my client is using is requiring 1000dpi. So this will be pretty huge at full size.

To get the pattern the size I want it without rendering a much larger size, I do need the scale node. I don't want to render an 180"w x 108"h file at 1000dpi and then crop it down. I don't even know how long, or even if my computer could render a file that size. I'm guessing you meant to oversize the image and then crop it down? Or you have some other method I'm missing?

I tried rendering a full size file yesterday (60000px x 36000px) in the v6 Trial and after about 20 minutes it locked my whole machine up. The force quit window popped up and said FF was paused. I quit all the other applications, but FF never came back online. I was trying to work while it was rendering. I guess I will have to let it run all night while I'm not trying to work in other applications at the same time. I'm on a 2015 5k iMac with 36gb of RAM.

I know, and I agree. I've told them this a few times. I don't know if the people at the print shop know what they are doing (it doesn't sound like it). In the end it isn't up to me to decide the print dpi. I just have to deliver what the client's print shop is asking for to get paid for the job. The customer is a go between for me and the print shop. Of course this would be much easier if the resolution was in a more normal range.

Thanks for the responses.

I thought the seamless textures how to be a square ratio?

Thanks for the reply Indigo Ray. I'll play around with the profile gradients and perlin noise settings. I'll be adjusting some of the texture settings in Photoshop after rendering.

Great tip on aspect ratio. This should come in very handy in the future.

I appreciate the help from both of you.

Yes, exactly SpaceRay! This is the goal that I've had from the beginning. So the main problem I've had is with scaling the texture. It looks great at th standard size, but the standard patten isn't large enough to work on a sign. If I can convince them that they don't need 1000dpi, it would make it easier to create a seamless tile.

Hi chrisd,

I haven't tried rendering the full size image yet as the client is still reviewing the options I gave them. I did try rendering a full size image about two weeks ago with the v7 beta and it locked up on me. Although to be fair I was running a bunch of RAM hungry apps (Photoshop, Illustrator, etc.) and still trying to work at the same time. So the next time I run it I will make sure no other apps are being used. I'm not sure if having a large amount of scratch disk space would help either? When I go to render this again I'll pop back in and let everyone know how it goes.

I'm on Windows but only have 17Gb ram. My system was using swap space when I did a test render at 30,000 x 30,000. I'm not sure it would ever complete on my system at the full resolution you need, although half the size might be doable.


Unchecked tiling and set to 30000 x 18000, using 13Gb, at 10 mins in its about 1/3 done. No swapping.

Sure, guess I'll have to add more memory on the next system if I ever want to go that large. This one maxes out at 24Gb, but its 6yrs old.

Just an update. I ran it at 800dpi and it also worked. I don't know how long it took though as I left my machine running over night. I wish there was more info on render times etc.

Thanks Indigo. I'll check on that setting. Is there a log file anywhere of render times or is it just a temporary notification?
