As a Roblox developer, it is currently too hard to create some types of visual effects.
There are some types of common visual effects that are very difficult to create in Roblox. I have wrote about this before, and so I have narrowed down my wish list. The visual effects listed below are some of the top effects that I think can benefit Roblox.
1. Ground Projections
These are graphics that can be projected onto a surface or terrain. They are commonly used as spell effects in games that use magic.
Bubbles with effects such as reflectivity, light emission, particles, ground intersections, etc.
3. Better Fire & Explosions
I think the current Roblox fire and explosion are as generic as it gets. Would it be possible to upgrade these or allow options for more interesting and varied fire and explosions.
4. Animated Textures / UVs
Animated textures are textures that are applied to a mesh and are then animated. Animated UVs are similar but animate the UVs associated with a mesh. Both of these are typically used to created special visual effects. Animating the texture or UVs gives the texture a dynamic and live feel.
5. Sprite Sheets
Sprite sheets are used for many things including creating visual effects. These are very popular in game engines, and would be great to have in Roblox.
If Roblox is able to address your issue, how would it improve your game and/or your development experience?
I think Roblox is still playing catch up in the visual effects department compared to other game engines. With more visual effects available to developers, Roblox games would look much more visually appealing.
