[How to] make textures for rendering??
-
Hi Guys,
I've seen some nice textures being posted here [Shaun for one] and an inspired to try making one.Say I have this image:
I want to paint the upper floor of a building as a 325mm deep horizontal siding.Is is better use the photo as a texture? If so what is the best way of doing so...?
or,
create your own from scratch. If so say I use GIMP [which I have] how do you do so....?Thanks in advance.

I use photos for all my textures, either ones I've taken myself or from the web. I use Photoshop but I'm sure Gimp will work just as well. I try to start with a good base pic, not much shadow or highlight cause I have a real hard time evening out the lighting, though alot of people do a good job at it. Modelhead posted a good tutorial for making textures here on the forum awhile ago. Then I crop the part that I want to use, then the offset filter, then either or a combination of all, the clone tool, healing brush, blur tool, to make it seamless. Then if my orginal pic is big enough, I'll pick another part and repeat the whole process then combine the two seamless pics, this helps to avoid tiling. If my orginal pic isn't big enough, then I'll make same slight variations to my seamless pic and combine those two. I have trouble fully explaining myself sometimes so here is a good tut, http://www.bitbrush.com/tutorial1.html

Cheers Mike. I'll take a look.

Mate for your siding it would depend on your render engine and whether it supports displacement?
That is certainly a case for displacement there! If you were to just use a texture map you will get a fairly flat result!

Hey Richard, using Podium.....
supports displacement?????? HEEEELLLPPP??????? -

I'm a Maxwell user it supports displacement though displaces your patience at the same time, slows renders to a hault.Mate seriously I'd just model it! I do this with brick panels, I just have a primative with my texture double click an using the PP tool just bring it to the edge of the window, I don't actually use hole cutting components for windows.
I just find it SO MUCH easier to do then chasing map placements etc! And for rendering you will get proper shadow cast from the material - which if wrong if just using a texture will look like crap. And trust it is SO MUCH FASTER!
See in the image here I've just pushed the lower brick panel away so you can see what I mean. Yeah I know the sill is incorrect - should slope - lazy!
-
Here you go done in two min, just make add more or less panels if you like.
I just made a rectangular primative, push top edge in, made all to a group copied up multiple times exploded, erased joining edges and grouped all. Because you may be using just colour now you can stretch the group horizontally.

utiler: podium does not support displacement.
unfortunately it only supports bumpmap/specmap/diffuse map
I would model it like richard says, wont take long at all.

Richard - thanks, did consider that but I'd say it might take new while to model the cladding across the upper floor of this place.....
skillion roofs with rectilinear walls make most wall tops sloping. Hence looking for an easier way to just create a texture.....Oliver, thanks for the Podium info; I might see if i can work out how to create a simple texture in GIMP......

Mate thats about a 20min job and the results will shine!
To do it in Gimp (assuming same as Photoshop) -
Draw out a rectange - use the paint bucket tool to fill with colour,
Copy up page multiple as separate layers,
Apply drop shadow to one of the intermediate layers and play with shadow settings and direction to cast direct depth,
Copy layer style and apply to other layers,
Using rectangular marque tool to select area which ends up half way through top and bottom boards, then crop - you need to do this otherwise the drop shadow will be absent from the vertical repeat.Now a good render artist would also take advantage at this point to make his texture map full height of the wall, over the top of the base texture image they would add a grunge layer (very subtly) to mimic streaking of water / dirt down the wall. Pays off but keep it subtle!!!

Hey cant you run that centre downpipe from the top roof onto a spreader onto the deck roof rather than running it through and down the wall?

Sure, good point. Might do that.....

Initially I was feeling lazy and wanted an easy way out but knowing my abilities with PS [or GIMP] I think modeling will be fine!!

modeling it will always look better. you only need to texture each 'panel' then and you won't need to make one for that.
