I have released version 1.1 for the blaze add-on and with this update, this shader becomes more awesome, you will get some improvements in the shader like you will have a new preset which will help you to create more detailed flames and this will add a lot more to the realism.
Another improvement is smoke, so you can control the thickness of smoke and much more things with this update and many more improvements are done.
So those who have already purchased this add-on have got the update for free and those purchasing now will get updated version.
