First displacement test
-
I thought I'd have a go to see what results I could achieve myself with displacement maps!
This test as my first was a great learning curve (thanks to Mihai and KurtS - maxwell forum for some tips). The difficulty was all in the creation of the double graded map for the ridge capping tile and the offsetting of this map when displaced to intersect correctly with the roof tile displacement.
I have graded back the roof tile edge of the displacement map and put a solid colour anlong that line of the colour map to avoid the stripped edge to the tiles that would normally occur to the displaced edge! Similar was utilised to get the mortar bedding under the ridge tile!
Seriously it took about half an hour to do the roof tile map correctly and maybe over a day to get the capping tile map right as it was quite a test! Still need to work out the best way to do the capping ends!
-
great
can you make some chinese roof with your displacement tecnique
give me some tutorial -
Nice one, it looks very convincing.
Could you post the displacement map by any chance?
-
Great! Sir, where can i get displacement maps? and BTW what software?
is it possible in kerkythea? -
Use displacement

I believe not for the moment
Blender without problem
Make a Displacement Map any prog 2D can do: it's a grey level image
-
As Frenchy points out the map is a simply devised greyscale map!
I made the maps in PhotoShop applied to very simple SU geometry and exported to maxwell.
-
Nice work Richard, it makes for a really good detailed roof.
-
Hi Richard,
That looks very realistic to me.
I love the way you 'handcrafted' the displacement map in Photoshop. -
Great work mate! I am very impressed with Maxwells use of displacement. I am going to try and recreate with Vray, but I doubt it will come close.
-
i got inspired and did a vray tests, looks great.
Thank you for your inspiration, great work -
Richard.
Very impressive control over a displacement map indeed, however how practical is such a workflow?
Would it not have been faster to just build the 3d mesh instead? how about render times? would this method not increase the render as opposed to a straight texture on a 3d created tiled roof?
-
very nice displacement and also your displacement map that you have.
-
Thanks all!! I can suggest lots of trial and error on this test!!!
Pete!
Mate I have till date modelled tiles though it is a real hassle given it would be easy if each could just be a component though it ends up that the end tiles often need to be trimmed back or they project out past the capping tile!
And obviously in SU the poly load from the tiles isn't handled well and not so bad with shingle tiles but once the tile has an intricate surface profile it can really blow out! In this case I just have to paint geometry!!! I found if I subdivide the roof well (just running a cookie cutter geometry through it and intersect with model) the rendertimes aren't significantly increased! Must say just painting a texture is really a far more simple process and where the roof becomes complex the saving really are great! And it also means I can paint dirt onto my large scale map and introduce some up and down variation in the tiles!
Hence in all the workflow is VERY simple!
-
impressive test, Richard.
especially the "up and down variations" seem a convincing reason for using displacement to me. adding "imperfections" surely is a lot easier than modelling it.

Thanks again PLot!!!
Yes slight offsets, rises and falls, chips and irregularities that all aid to increase realism at no additional modelling time is a real bonus toward the use of displacement. As well as the simple dealing with SU's poly limits.
With the last few renders I've done having the main context dwelling and a few surrounding dwelling with modelled tiles SU would crawl to a stand still once the tile layer was turned on! With just mapping and very simple geometry it will be a god sent!
-
Another quick test with different tile profile! Just quick few minute render!
-
another marvellous displacement example, Richard! absolutely convincing.
is it possible with Maxwell to have layered textures with different UV coordinates within SketchUp, as you can do with Indigo?
or are the (truely beautyful) spots of dirt on your first image part of the roof tiles texture and will be repeated in a regual pattern? -

And yes the option is there to offset or call upon a different repeat to any map used, unlike indigo maxwell can also utilse weight maps so the option is also available to place a large map over the whole roof and provide streaking or dirt where you want it exactly and then repeat the tile texture under that! And only one map needs to be present in the SU model!
I would never want to draw the short falls of Indigo as it has some amazing development but the containment of maps within the model and lack of weight mapping is a real bummer! I look at my low poly cars as an example and the same outcome can never be achieved with the current setup required within SU!

Hi Richard!
Impressive tests, i must say!
But, tell us: i once tried maxwell's displacement capabilities, but the result was indeed very odd. Then i read that the displaced surface had to be subdivided into smaller triangles for maxwell to displace it properly. Has it been fixed, maybe? Or you simply subdivided you roof surface a little bit?
I think some SU screenshots would help a lot!
Thanks! -

Here is an image of the SU model - I have cut a bit of the roof away so you can see how the capping goes under the tile.
Subdivision of the surface is not a must but what it means is without the surface subdivided you will need really high precision levels to get the best outcome which will greatly increase render times.
To example - when I started this test I didn't sub div the surface and had to apply a precision of 2500 to get hard edges to the tiles. If I selected the adaptive option (which generates the best quality the res of your map will permit) the redner ran for an hour but still didn't start due to the calcs still running! Once I did some very simple sub div with adaptive option selected it cranked up in about three minutes!
