I need to add a bubbled paint job texture to a TARDIS model I've built but I am REALLY struggling. Please help!
The standard procedural textures either don't hit the mark or look too uniform, and I'm at a loss to work it out.

Is this your render?

Forget procedural textures, this has to be created properly in a paint program or sculpt program or what ever, procedurals always look like procedurals. UV map the tardis and get painting.

Thank you both.
danielkaiser - I wish. This is what I want to recreate.

djwaterman - I suspected as much, I'll go back to that drawing board. I've tried a couple of things but they really didn't work out but I'll get back on that and read up about bump and deformation. I was even considering making the lumps/bumps as objects and scattering them around the model so that they just poke out of the models surface but I figured that would take a while, involve making many different lump objects and significantly increase render time. I was desperate to do this to meet a deadline but I missed that so I can get this done at my own speed. In terms of sculpting programs, any recommendations (preferably cheap/free)?

There's plenty of refs on Google images and other free textures sites, doors are quite easy to UV too so you just need a little bit of time and patience. Do you know anything about creating your own texture maps?

Thanks 50one.
I've made a displacement map for a landscape once...badly but presumably I'd bake a uv map, open in Photoshop, make it hi-res and add the details? I'm still new at this (does it show?)

No worries, you are in good hands:)

I would start with 3 maps . diffuse(colour) then do specular and then displacement - use the free version of NDO v1, you can still find it online - it's a normal map generation plugin that is an action for Photoshop.

It's definitely possible using procedurals.

The peeling paint effect I did in my short film https://www.youtube.com/watch?v=WOqhTstIpHY was all procedurals.
A low res still here:

Just a case of using the right one, inverted crumple is pretty nice, and using other procedurals or image maps to mask them for irregularity.

Indeed, and a bit of EE_gritnode works wonders as well.

Bad procedurals look like bad procedurals. Whether they be a poor setup or poor programming. But I would agree that painting a paint effect would make the most sense.

Plus baking a procedural to texture can give you a good base to start from but so can a good photo.

Indeed Sir, mixing procedurals and photo is the way to go.

Thank you all very much...unfortunately (as is usually the case for me) I am really struggling to locate NDO or Grit Node
I looked for NDO and I got this http://www.philipk.net/ndo.html which then took me to http://www.cgted.com/ which just seems to send me in circles
I looked for EE Grit Node and found http://katastro.fi/~eetu/gritnode/ but the site 'cannot be reached'. I found what appears to be a Mac version on this forum but I have PC

Unless you guys know where else I could get one or either of these, I'll have to go with UV map / painted texture route

Roger that, which is exactly what the substance workflow philosophy is. I was immediately attracted to it when I saw those allegorithmic nodes.

vortexvisuals I believe you are looking for the Quixel suite tools?

I was talking about ndo which was free and later evolved to be part of quixel suite which is a paid set of apps.

There used to be a free version of those tools. I guess they are gone now.

Here's a script for PS, maybe it still works.

Nvidia has a normal map tool.

Thank you guys so much for all this.
jasonwestmas: Thank you for the script, which works, I just need to put together a decent image to apply it to as my source images didn't really work that well.
Once I've cracked it, I'll upload a render so you can see how much you've all helped.
I'm gutted that I can't get at the EE Grit node but there you

They are still free, but they removed them from their site. It is up to users to keep track of these versions themselves.
You can still find them via the webarchive:
