Knowing how to use the blender tutorial for your 3D modeling is helpful because you need to know to make the lighting on the design look good. The lighting goes far to help you when you are trying to make your design look better, and you need to be with someone who will help you make the best decisions for the design in your hand. The design that you make cannot be perfect until you have gotten the lighting right, and the blender tutorial saves you so much time that you will never have to worry about not finishing on time.
You are on a deadline that relates to your payment, and you need to have a program that lets you get everything right the first time. You send it off to your client when you are done, and they will be impressed because they see something that looks complete. You need to play with the lighting until you see something that looks realistic. You are trying to turn a 3D model into something that you can see in the real world, and you will enjoy it more every time you finish. That design goes in your portfolio along with your other work, and you will look back and remember that you did such good work.
You will need to use the blender every time you do a new design, and you have to learn that light plays an important part in what you design. The design is not done in the dark, and there is no static light for it. You are using these things to make your life much easier as you do your work, and you need to know that you have options that go outside of the boxy 3D design that you are used to seeing.
3D models you create are helpful because they solve your problems for you when you are completing the design. You need something that shows you every nook and cranny of the design, and you will start noticing parts of the design you never thought of before. You need to have something that will help you when you are trying to complete the design, but you also need something that susses out all the errors. You will make mistakes as you are drawing, and you cannot avoid them. You catch them when you have 3D models right in front of you that show you what is going on.
You want to have these models ready to go for other people so they can check them for errors. Your errors get much worse when you do not catch them the first time, and you go on with that error for a long time without any way of fixing it. That is a major issue that you need to solve before you get too deep into the program, and you need to start considering how you will make changes to the model.
You are working with people who will expect you to make changes once you find errors, but you will avoid most errors after checking in a software program. The best programs will help you find errors that make no sense, and you will find a few problems that make you change the whole idea. This is the only way to design because everyone who works in the 3D modeling business does the same thing. They expect to see the design change a few times before it is complete, and they expect you to check it for errors. You can do both of these things using one piece of software that you find online.
