Some of the worlds most exciting 3D artists share their top tricks and pro tips to help you master modeling and become an all-round better artist

If concept artists are the dreamers of the 3D world, then the texture artists are the detail guys. These are the people who believe not only in dotting every i and crossing every t, but polishing every blade of grass too, and giving even the newest and cleanest tank a tiny spot of rust. And if thats naturally you, then you probably love giving your work texture. If its not naturally you, then read on, and see if what our experts say inspire you to mess up those models a little.

"You dont need to create all the tiny details in your sculpting software. Many times, especially when texturing cloth or other types of small tileable details, I use Photoshop to add those details José Alves da Silva

Tip 1: Hair today, gone tomorrow

I model the hair meshes on my characters as neatly as I can, making the topology flow like real hair would. This way, I can UVUnwrap the model, straighten out the topology strips and then simply use a stretched (or motion blurred in Photoshop) noise texture to create the look of stylized hair strands. Andrew Hickinbottom

Every strand of hair is worth working on

Tip 2: Organic options

Useful tools like the Dry brush in Mudbox (and similar brushes on equivalent software) can help quickly to paint worn-out zones in organic and non-organic surfaces. Since it can grab only peaks or valleys you can easily paint the zones of the object that are more exposed and therefore more susceptible to damage. Along with a cavity map you can quickly paint rust on hard surfaces or dust/dirt on organic objects. Carlos Ortega Elizalde

Tip 3: PolyPaint in ZBrush

To PolyPaint my models I use a simple scheme I created. 1 is the main color; 2 is the secondary main color; 3 is a lighter and darker variations of the main colors; 4 is a warmer variation of the main colors blended with the color of the blood; 5 is a desaturated variation and 6 is the pattern colors. Luca Nemolato

Plan your own way of doing things, but have a system to keep your colors and textures clear

Tip 4: Overlay details on Normal maps

You dont need to create all the tiny details in your sculpting software. Many times, especially when texturing cloth or other types of small tileable details, I use Photoshop to add those details. With free software like xNormal (which installs a set of handy filters in Photoshop) you can convert a Bump map into a Normal map (Height2Normals). Then just add this Normal map on a new layer on top of your original Normal map and set the blending mode to Overlay. Change the Fill value percentage to control the intensity of the details. José Alves da Silva

Does the detail need to be on the model, or in the final image?

Tip 5: Exporting hair guides from ZBrush into 3ds Max

You can replicate the hair created in ZBrush with FiberMesh in 3ds Max by exporting the hair curves and using them as guides for the Hair and Fur modifier in 3ds Max. In ZBrush, in the FiberMesh menu, choose Export Curves and save it as an OBJ. In 3ds Max, choose Import from the File menu and choose the OBJ file. In the OBJ Import Options enable Shapes/Lines to be able to import the splines and also enable Import as a single mesh so that all splines are attached together into a single object. Press Import.

"Select the splines object, change the sub-object selection mode to spline and select all splines. The total number of splines shows up in the modifier (at the bottom of the Selection menu). Memorize this number. Apply the Hair and Fur (WSM) modifier to the splines. Set Hair count to the number of splines you have memorized. Disable interpolate. Set Rand. Scale to 0 and in Frizz Parameters set Frizz Root and Frizz Tip values to 0 in order to remove any randomness. Done! José Alves da Silva

Hair can be tough, but it can also be manageable

Tip 6: Paint and perfect

To create textures, I have the BodyPaint exchange plug-in to send the 3D models from 3ds Max to BodyPaint 3D. With this software I can paint and have all the tools needed to create and paint in real-time all the textures such as the Diffuse, Reflection, Bump and Normal map etc. In this way, I can create fine details for the 3D model textures and effects.

Tip 7: Do what you can

Complex scenes are sometimes composed of hundreds of objects, and the time it takes to make clean UVs and texture every single individual asset would take forever. Because of this, I tend to texture only objects that have high importance in the camera view. If something is in focus and has strong visibility, I will make clean UVs, paint detailed textures in Photoshop and create very detailed materials. For other objects, a combination of tileable textures, procedural noises and variation of textures per object is my way of dealing with complexity. Bercon maps can be great for randomizing textures on objects. Vertex painting in 3ds Max is also a great way to paint dirt maps of objects without the need to have good UVs. Toni Bratincevic

Tip 8: Make light work of lighting

Without proper materials in place, creating an appealing image will prove extremely difficult and the lighting (which is all about showcasing a character and/or a set) will feel like a drag. Well-built materials and textures will add visual variety to a shot and make lighting feel effortless. Francesco Giroldini

Textures are a critical part of your shot, and aid your lighting attempts too

Tip 9: Give it gloss

Glossy reflections are one of the most computationally expensive and yet indispensable elements to a convincing image and their absence can break an otherwise solid shot. Francesco Giroldini

Reflections are one of the trickiest things to get right

Tip 10: Get the feel

When setting up your shaders always balance how diffusive vs reflective a material is. Very diffusive materials are likely to feature very dim and blurry reflections while very reflective materials are likely to not catch or bounce much diffused light. Francesco Giroldini

Thinking about real world examples is always key when it comes to texturing

Take your time

One of the great things about texturing work is that like modeling bits and pieces of it can always be re-used in the future. So putting the time and effort in now can really pay off, when you then have a massive bank of textures you can pull from in the future. And, of course, practice makes perfect, so the more you work on these details, the better theyll come out. And when youre done itll be time to light your scene and show off your handiwork, as our experts reveal their Top 10 lighting tips in our next installment...
