Q & A

What is the process of 'gamification' that is referred to in the script?
-Gamification refers to the process of making game textures and assets look old, used and gritty instead of clean and new. It helps make the game look more realistic.
Why is gamification an effective and commonly used process in game development?
-Gamification is an inexpensive way to add visual interest and realism to a game. Dirty, gritty textures are effective at making a game world seem lived-in and believable.
What are some examples of textures that are gamified in the script?
-Examples of textures getting gamified include the hotel carpet, walls, floor pads, and the main character's hands and weapons.
What is the purpose of exporting the UV map for the character's arm?
-Exporting the UV map allows the developer to see exactly how the texture is mapped onto the 3D model. This helps guide editing the texture correctly in Photoshop.
How are the shine/smoothness maps created for the character's hands and weapons?
-The shine/smoothness maps are created by copying the base texture into an alpha channel in Photoshop. White areas represent shininess, black areas represent no shininess.
What is the purpose of adding scratches and cracks to the game weapons?
-Adding subtle scratches helps make the weapons look used and battle-worn instead of brand new. This adds realism and visual interest.
How can normal maps help enhance texture details?
-Normal maps can simulate surface details like bumps, cracks and scratches without heavily taxing game performance. They efficiently enhance textures.
What sale offer is promoted during the script?
-A 50% off sale for the presenter's Full Time Game Dev course is promoted. This comprehensive course teaches game development and how to secure game funding.
What game engine is used during the texture editing demonstrations?
-Unity is the game engine used to show the texture editing workflow.
What is the purpose of the free 2D game art kit offered at the end?
-The game art kit allows viewers to make their own 2D games for free. The presenter used a past version of it to make a popular YouTube game.

🎥 Introducing the video and topics to be covered

The video introduces the creator, Thomas Brush, and the topics to be covered in the tutorial video. He mentions they will be doing texture work to make a boring level look more interesting. He also promotes his Fulltime Game Dev course and a free 2D game kit.

05:02

🖌️ Adding stains and grime to carpet textures

Thomas begins adding grimy stains and textures to the carpet on the walls to make them look dirty and worn. He uses overlay and multiply blending modes and makes sure the textures tile seamlessly without wrapping issues.

10:04

🎨 Modifying pillar textures and colors

Thomas changes the colors and textures of some pillars in the scene to make them more playful and unique, moving away from a boring flat texture. He tries different colors like purple and pink to give them a creepy toy-like vibe.

15:07

🔳 Adding grid pattern to ceiling texture

Noticing the ceiling texture is boring, Thomas adds a grid pattern to create visual interest. He compares it to the game Portal. The strong highlights and shadows make it look stylized and hand-painted.

20:08

🖌️ Painting wood paneling onto walls

Thomas adds painted wood panel textures to the walls to give them more interest. He adds normal maps, shadows, and highlights to give them depth. He applies it carefully to avoid tiling issues.

25:10

🩸 Adding grunge to character's hands

Thomas starts adding grime and texture to the main character's hands to make them look dirty and match the scene's aesthetic. He adds scratches, bumps, and shininess to the fingernails for realism.

30:14

⚔️ Texturing a bloodied axe

Moving on to weapons, Thomas adds grunge like cracks, scratches and rust to the axe texture. He pays special attention to make sure the textures tile properly. He adds shadows and bumps to make the blood look elevated.

35:14

🔎 Inspecting changes and seeking feedback

Thomas does a final fly-through of the scene, inspecting all the texture changes. He takes screenshots to share with his team and get their feedback. He also promotes his courses one last time as the sale event ends.

Keywords

💡Gamification

Gamification refers to the process of making game environments and assets look old, dirty and grimy. As the narrator explains, this is a common technique in games because it is cheap and effective for creating atmosphere. He shows examples of adding stains, mold, cracks and other imperfections to the hotel textures to make them look worn-out.

💡Textures

Textures refer to the surface details that are mapped onto 3D models in games. The video focuses heavily on editing textures by adding effects like stains, scratches and normal maps to make surfaces look grungy. The narrator explains that texture work has a huge payoff in enhancing game visuals.

💡Normal maps

Normal maps are special texture files that create the illusion of depth and texture without heavy modeling. The video shows generating and editing normal maps from base textures to add apparent cracks and grooves on surfaces.

💡UV mapping

UV mapping refers to the 2D layout of a 3D model's surface topology. The narrator exports the UV layout of the character's arm to use as a reference for painting grime onto the diffuse and normal map textures. This ensures it maps correctly onto the 3D model.

💡Full-time Game Dev

The Full-time Game Dev course that the narrator refers to teaches game development skills like coding, art and securing publisher funding to become a professional developer. He mentions that it's on a 50% sale and has trained many successful alumni over 4,200 students.

💡Smoothing map

A smoothing map defines how shiny different parts of a texture are. The video shows editing these to make the character's skin look sweaty and oily in places, while keeping other areas matte.

💡Metallic map

A metallic map defines which areas of a texture should look metallic or like metal. This is edited on the axe textures to make the blade look worn and rusted.

💡Albedo map

The albedo map contains the base color and shading of a texture. The video shows editing these, like increasing contrast on the wood, and layering detail textures to create grunge.

💡Alpha map

Alpha maps define transparency and edges for textures. The video shows using alpha channels to store gloss and metal information as grayscale maps for application to materials.

💡Tiles vs. Unique textures

The narrator distinguishes between reusable tiling textures that repeat across floors and walls, vs. unique textures mapped to specific objects. He avoids details like wallpaper peeling that would look repetitive when tiled.

Highlights

The study found that young children who were exposed to diverse foods early in life were more likely to have healthier diets.

Researchers assessed the diets of over 1,500 children at ages 1, 3, and 5 by surveying parents on foods consumed in a 24-hour period.

Children with high food variety at age 1 consumed an average of 15 different foods per day at age 3 compared to only 8 foods for low variety infants.

High variety infants were more likely to eat vegetables, fruits, and proteins while low variety infants consumed more sweets and snacks.

The food variety effect was still seen at age 5, suggesting early exposure shapes long-term eating habits.

Researchers controlled for factors like breastfeeding duration, income, and ethnicity to isolate the impact of early food variety.

Experts recommend gradually introducing a wide range of healthy foods to infants over their first year to promote lifetime healthy eating.

The study provides evidence for the benefits of early exposure to diverse, nutritious foods on children's diets.

The findings support health guidelines for introducing solids between 4-6 months and offering a variety of foods.

Researchers plan to study potential factors driving low food variety in infants like parental feeding practices.

Experts emphasized the importance of repeated exposure to unfamiliar foods to increase acceptance over time.

The study highlights the critical developmental window for shaping taste preferences through early feeding.

Further research is needed on interventions like parenting classes to increase food variety for picky eaters.

Experts say a wide variety of nutritious foods should be part of complementary feeding for optimal nutrition.

The study underscores the long-term impacts of early feeding practices and the need for guidance for caregivers.
