I made an article about photogrammerty a few months back, but have learnt a few new things since, so it's time for a revamp !

Here is what I came up with :

My new render

The old version
## How it was made
I first imported the raw model, textureless
![](/images/textureless.png)
{{< figure align=center src="images/textureless.png" alt="Alt text" title="The textureless model. Really does not look good like this." >}}
The textureless model. Really does not look good like this.
Then I added the raw texture

{{< figure align=center src="images/textures.png" alt="Alt text" title="This is the texture only. Better, but lacks realism." >}}
This is the texture only. Better, but lacks realism.
I created a material, and used the nodes to configure it :

Some nodes to set material properties

{{< figure align=center src="images/material.png" alt="Alt text" title="Material loaded !" >}}
Material loaded !
There is a rougness which depends on the darkness of the texture : the darker, the smoother.

I added a bimp map to create little bumps where the texture was the darkest. That added to the realism of the tree bark, and created some wear on the statue itself.

I added a background HDR from [HDRI Haven](https://hdrihaven.com/), awesome website, I really recommend ! It's all free to use high quality material ! [Feel free to help their patreon page](https://www.patreon.com/hdrihaven/overview)

Then  I played with the camera settings, finding a nice view, setting the focus point and opening the aperture for the background and foreground to be a bit blurry.
And that's it ! I thing this result is way better than last time !

The final result !
