Right now, I am TERRIBLE at drawing, but I've always been intrigued about creating my own characters/level design, but right now I am working on programming, since making games myself would be quicker.

I am going to learn Blender 3D soon, do I have to be good at art to be good at something like Blender?

o.O Okay good at drawing != good at art != good at game design.

But to answer the question I think you're asking, using blender doesn't have a lot of skills in common with drawing. Unless you are trying to create something from scratch and don't have a photo or drawing from someone else to use as a reference.

It is a hard question to answer, honestly.

I cannot draw cartoon characters on paper and pencil. I am personally better at drawing vector first.
And technically, drawing things on your own may or may not save time. I've been working on a single
main character sprite for about 10 hours now and I still have questions. But I am quite pleased how
it's going n_n!

I never took art classes, and there is much to learn. However, I did start simple with simple graphics.
Good ol' NES graphics. Take a look at them. When you study simple textures like those, you come to
understand better the power each pixel has on a sheet.

Having that knowledge, bump yourself up to SNES graphics. Zoom in on those sprite sheets.

Once you play around enough, upgrade yourself to some good art programs (Photoshop, Paint Shop X3)
to help you make your images pixel-perfect!

It can take a lot of time trying to figure our the art aspects of your game. Don't let this discourage you,
only encourage to improve upon yourself!

Well, being "TERRIBLE" at drawing implies that you have a hard time to understand shapes. And that's a problem when you try to make shapes...
If you are overstating your bad skills, and you only have problems with the "implementation" of the drawing (i.e. your hands are clumsy), then it's okay. So I say you don't have to be good, but don't be terrible at it.

Small details are hard to make on models. Some can be extremely hard to make right, otherwise the light-shading will be screwed. Just think about fillets (round edges). Even the highest end non-polygon based design applications can screw that. And in polygon based programs (programs you use to create game assets), you have to make these more or less on your own. And meeting fillets can be a nightmare. And to make the whole work with lights (think about vertex normals) is another story. (for example for perfect looking fillets between flat faces, you have to add a thin polygon next to the fillet, and that has to be coplanar with the face. Otherwise the face will look screwed literally).

So long story short, you you have to be able to draw to some extent.

I would say no, but it helps.

Then again it's kind of a necessity if you want to be a concept artist Interestingly enough, the longer your work in 3D, your 2D will improve. Having great 2D skills will make your 3D easier (and better) from the outset, though.

If possible, I would get in a figure drawing class or two. Work on perspective drawing, and getting a good sense of composition, color, lighting, etc before I jumped feet-first into 3d. I didn't have much in the way of 2D skills when I started in the industry, but I was fortunate enough to work under some very talented fine-artists at the time. Anatomy, for example, is something pretty difficult to pick up on your own. Mine is still not where I want it to be,(as well as other things).

That being said if you want to jump into 3D, go ahead. But work on your 2D as well.

Finally, practice, practice, practice. Your skills will improve. Artists should always be concentrating on improving their skills. You'll get where you want to be. It just takes time, and a lot of hard work, so don't get discouraged.

Well i believe it helps a great deal if you are good or decent at drawing when starting in 3d but i know for a fact you do not have to be able to draw to be good at 3d modelling as i have a friend that i have worked with who can't draw to save his life and that isn't me just being rude he really can't and he is a great 3d artist he says he knows exactly how it looks in his head and he can't draw it but he bases the mesh out in Autodesk Maya to get the general shape and size of the character / monster that he is creating then he will bring it into Zbrush and sculpt it to look the way he invisions the model in his head

His models look amazing and usable for games as he just bakes the normal maps onto a lower poly version of his model

I however rely on a reference image to create my models as i can't just work from my head so i would have to go and sketch up my character front and side view then scan them into my computer and model the character based on that the good old fastioned way

So my answer is no you do not need to be good at drawing to be good at making models for games just aslong as you can do what my friend does and as for actual designing of the game i believe it really does help but again not essential

From a game design perspective, a picture is worth a thousand words. If you can show someone something visually, they will get the concept a whole lot quicker and clearer than if you were to describe it with words. I think as a game designer you need to be good enough at art to

1) Be able to express yourself visually and for you to be understood
2) Possibly to understand how the implementation of your ideas will affect the project timeline. For instance it will probably take longer for photorealistic 3d models versus doing something like WOW where it is cartoony and somewhat simple.

You should also understand programming enough to understand how your ideas can affect the project timeline. Of course you can always ask your Art Director and your lead programmer as well.
