Unless you are making a game where everyone else/ everything is supersized, and you play as a miniature thing, A dice is really achievable with just a regular cube and a decent texture.
Because, If it was all to scale, Not even the texture would matter that much?
You quite obviously are new to these forums, so just a little tip to help you out in future.
You will get a much better, efficient response with...
A) A proper thread title
B) In the title, and your post, you use proper english. thth duznt meen talkin lyk dis. It means using proper spelling, punctuation, and grammar. Its easier to read, and the more 'knowledgeable' members of the community really only choose to fully participate with those who speak properly.
But those aside, Welcome to the Forums

Hope to see some more contributions coming in, maybe a game or two also
